How Not to Brick a Samsung Galaxy Tab PT-3113 with a Kit Kat

This will only point out the obstacles that I encountered. Below are links that started my research and eventually successful install of the Cyanogenmod build 4.4 or Kit Kat.

First stop DroidCheats YouTube channel, which is an excellent resource in such matters. However, I followed his excellent step by step instructions but did not pay attention to the file versions that I was using, my first mistake.

This mistake resulted in further errors with the Android soft keyboard and thus the inability to type text into the tablet.

My second mistake involved tracking down the pop up dialog message, "Unfortunately Android AOSP keyboard has stopped." But, don't bother following any of the instructions that you may encounter, which was my last and final mistake.

Lesson learned: A successful install of Cyanogenmod build 4.4* starts with pairing up the right files.

So I started over again and followed the install steps that can be found at web sites like xda-developers and the previously sited DroidCheats YouTube channel.

Here are the files that I used and why.

cm-11-20131229-NIGHTLY-p1.zip : If I'm going to do this, might as well get Kit Kat.

pa-gapps-stock-4.4.2-20131215-signed.zip : After rebooting only with ROM installed, I discovered that the build version is 4.4.2, therefore I want the Google Apps install for that version.

That's it. Save yourself from panic and move slowly and purposefully.

int wordCount=wordsToShow.length;
@Override

Android 2,2 Fragments

Since my app at Google Play targets Android 2.2 or higher, there a few things that need to be in place for fragments.

import android.support.v4.app.DialogFragment; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentActivity;

ActivityThatCallsFragment extends FragmentActivity

Use getSupportFragmentManager() instead of getFragmentManager()

Android ArrayList, HashMap and Clickable ListView

I am coding a delete screen for the Android W.A.R. app. Get it here at Google Play before I break it.

Meanwhile, in order to list the geotags that can be deleted, I will need a list of geotags with "id" as the key.

So first, I use an Async task to make the HTTP call to my server and select geotags by "id". I will not show that proprietary code here, but I can show the Async's onPostExecute method where the following occurs:

Receive a table with two columns: id and title

Populate a HashMap with the columns named: "id" and "title"

Assign the HashMap values to an ArrayList

Send the ArrayList to a clickable ListView that uses android.R.layout.simple_list_item_2

Convert the ArrayList row back to a HashMap to retrieve "Id".

There must be a more elegant way to do this, but you get what you pay for. I do this for fun and for free.

Just the bare bones...

@Override
protected void onPostExecute(String[][] result)
{
final ArrayList> alist = new ArrayList>();
int size = result.length;
for (int i = 0; i < size; i++) {
  HashMap cols = new HashMap();
  cols.put("id", result[i][0]);
  cols.put("title",result[i][1]);
  alist.add(cols);
}
// release result table
result = null;
//Identify the column names
String[] from = { "id", "title" };
//Send corresponding values to fields in android.R.layout.simple_list_item_2
int[] to = { android.R.id.text1, android.R.id.text2 };
ListView delview = (ListView) findViewById(R.id.list3);
//Set up the adapter to hold the two column table
SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), alist,
      android.R.layout.simple_list_item_2, from, to);
delview.setAdapter(adapter);
adapter.notifyDataSetChanged();
//The Click Listener on each row
delview.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView parent, View view, int position1, long id) {
    Map mid = alist.get(position1);
    String sid = mid.get("id");
    Toast.makeText(getBaseContext(), "Clicked on tag Id: "+sid,
    Toast.LENGTH_SHORT).show();
});
return;
}

Enhancing W.A.R. - Widespread Augmented Reality

I have been busy enhancing my Android app on Google Play that uses the camera as a view finder to locate your friends at places that interest them, a.k.a. points of interest.

There are actually two apps: 1. Ice Cream Sandwich and lower; 2. Jelly Bean and up. This was necessary because version 1 was crashing on the Samsung Galaxy 3.

Below are typical screen shots of geotags in Los Angeles.

Note that this Android app also creates the geotags, so points of interest are relevant to your clique or set of friends. You can also create geotags remotely with the companion website at SpiderOnFire. Your W.A.R. handles are anonymous and all content can be deleted at your discretion.

Implementing the Android Dialog Fragment

This is how my code works for a Yes|No fragment dialog box when clicking an item in the ListView activity. Download the full source code here. GitHub repository here.

Android Fragment Class Coded Directly on Samsung Galaxy Tab 7 inch

Using AIDE and Droid Edit to create extra class files in the AppProjects directory, I threw together a simple Dialog Fragment class like so:
I. Filename: MyDiagFrag.java

public class MyDiagFrag extends DialogFragment {
Context myContext;
public MyDiagFrag() {
//myContext = getActivity();
//empty constructor
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder aDb = new AlertDialog.Builder(getActivity());
aDb.setTitle("Delete");
aDb.setMessage("Sure about this?");
aDb.setPositiveButton("Yes", null);
aDb.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface d, int which) {
d.dismiss();
}
});
return aDb.create();
}
}

II. Filename: DataActivity.java

public class DataActivity extends Activity
{
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.mainlist);
ActionBar actbar = getActionBar();
actbar.show();
actbar.setDisplayHomeAsUpEnabled(true);
// Declare Screen output
// Bunch of code omitted for this example...
lv = (ListView)findViewById(R.id.list);
lv.setAdapter(mAdapter);
lv.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView parent, View view, int position1, long id)
{new MyDiagFrag().show(getFragmentManager(), "MyDiag");}});
// More processing omitted for this example....

Final, Adventures in Coding Directly on a Samsung Galaxy Tablet 2.0 - 7 Inch

Here are my final tips for using AIDE to code Android apps directly on a Samsung tablet.

Use a File Manager to copy folders among projects.

Remember that the software may not always track your changes in real time, so use AIDE's action bar menu | More | Refresh Build.

Also, you may need to exit and close files occasionally to synchronize all your changes. It seems that the built in code hints occasionally conflict and override manual edits.

Despite closing this thread, I still intend to use AIDE for my Cash Tracking app with SQLite and to code fragments that integrate my thirteen stock and options trading apps at Google Play

Cont'd, Adventures in Coding Directly on a Samsung Galaxy Tablet 2.0 - 7 Inch

I must report that I have had to reinstall AIDE three times due to unexplained crashes, but I do not mind as I have had good practice coding on the soft keyboard. Another caveat, this app is no Eclipse where you can easily configure the build path and import .jar libraries. In conclusion of this thread, coding Android apps directly on the Samsung Galaxy Tablet 7 inch, I have been able to write simple constructs with fragments, compile source and run  .dex modules from the palm of my hand. This is all I ever expected.

Cont'd, Adventures in Coding Directly on a Samsung Galaxy Tablet 2.0 - 7 Inch

Back to plugging away at this simple cash tracking app with SQLite, I discovered that AIDE has an option called Refresh Code Anaysis under the action bar menu icon and More. However, I must warn you that serious run time abends have frozen my tablet and forced a hard reboot (power and up volume keys). In future posts I hope to share an elegant solution that will dump the log cat and force close the app. BTW, I still refuse to buy a keyboard as it negates the purpose of a tablet.

After a half hour of puzzlement trying to debug a new XML layout, I realized that when creating a new file in the res/ folder, you must include the file type e.g., main_row.xml not just main_row.

Welcome back. The previous posts on this subject failed to include a Teminal Emulator app and SQLite3.

Developing on a rooted phone, I have found these tools to be essential as my programs send and receive data to SQLite. The root process is not included here.

From a terminal window command line, I enter the following lines to view SQLite data.

su

cd data/data/"insert your app package name"/databases

ls

sqlite3 "insert your database name"

.tables

While on an SQLite> command line, you can enter the usual "Select" and so forth SQL commands.

Specific design and coding challenges are forthcoming.

Continued from the August 2, 2013 post.

After creating a project folder and using the "Create a new App Project here..." option in AIDE, I found that the built in editor is not as robust as using a third party code editor like DroidEdit. You will see what I mean when trying to insert a new line with the [Return] key. To be continued...

I recently transitioned from strictly programming to retail sales of computers and peripherals. This requires a significant learning curve as my minimalist existence precludes me from possessing the latest technology with all the bells and whistles. For example, I do not get text messages nor do I own a smart phone. Oddly enough, however, folks trust my ability to help them, because I look Asian, where glasses, assess their needs and logically explain what I would do given their requirements.

Record Android Screen to PC for Presentation

This instructional assumes that you are a developer who already has the Android SDK installed, has a c:/Java folder with JDK, JRE6 and JRE7, has an Android phone set to debug mode and has an Android to PC USB connector. If you identify with the above characteristics, then all you have to do is the following.

1. Download great program called Droid@Screen
2. Save the "droidAtScreen-1.0.1.jar" to a folder like "../Downloads"
3. Set up your environment variables by clicking [Start], type "Environment" and then click [Edit system environment variables]
4. Add entries for ANDROID_HOME and ANDROID_SDK_HOME with the paths set to c:/android/platform-tools/. Or set it to wherever the ADB (Android Debug Bridge) program is located.
5. Open a command line window by clicking [Start] and typing "command"
6. Navigate to the folder containing droidAtScreen-1.0.1.jar and type: "java -jar droidAtScreen-1.0.1.jar.
7. Start your Android device with the USB cord plugged in to the PC.
8. Enjoy the fantastic tool created by Jens Riboe

Android, Eclipse, Memory Analyzer Tool (MAT)

Been a little while since I last needed to analyze memory leaks on an Android application written in Java and compiled through Eclipse.

Things have changed in both Eclipse and MAT, so I am listing my current steps here for all to enjoy.

---

1. Fire up Eclipse Indigo with Java 6 +

2. In Eclipse, Select [Help] | [Install new Software]

3. Add http://download.eclipse.org/mat/1.2/update-site/.

4. Select All []IDE and []Stand Alone

5. In Eclipse top menu bar, select [Window] | [Preferences] | [Android] | [DDMS]

a. HPROF Action: "open in Eclipse"

6. In Eclipse top menu bar, select [Window] | [Preferences] | [Plug-in Development] | [Target Platform]

7. Highlight Active Platform, then press [Edit].

8. Click [Arguments] tab: Type -XX:+HeapDumpOnOutOfMemoryError in VM Arguments,[Finish]

9. A heap dump is written on the first Out Of Memory Error.

10. Run project with emulator as the process must be on the local machine.

11. In Eclipse top menu bar, select [Window] | [Open Perspective] | [Other] | [Memory Analysis]

12. From inside the Memory Analysis perspective select [File] | [Acquire Heap Dump]

13. [Configure] | Select HPROF -jmap dump | -jdkhome = C:\Java\jdk1.7.0

14. [Next] | Select HPROF -jmap dump | [Finish]

15. Follow remaining prompts in Eclipse.

Compare and augment the previous steps with BonitaSoft.org

Also, try to perform these steps on a machine greater than an Acer Aspire netbook with 1GB of RAM. Otherwise, the process could take days.

Metaio's Jaw Dropping Augmented Reality Technology

Culled from Augmented Reality Daily.

W.A.R. - Widespread Augmented Reality

Imagine leaving your images, comments and content hovering at or above real physical locations. Imagine others nearby interacting with your marks through their cameras. In fact, imagine scanning the horizon or your surroundings with your own mobile camera to reveal the floating marks left by others. Well stop imagining and do it with this app. The possibilities are endless with the sky as the limit. The Android app is in beta at the website SpiderOnFire. One can use the website to place markers at locations without having to be there. The Android app's camera view reveals content beyond your line of site. After testing and adding more features, the app will be published to Google Play with mad props out to MixARE for providing the augmented reality engine.
