This is by far the best documentation of Google Maps API V2 vs old Google Maps.

Now I am almost ready to publish latest version of Widespread Augmented Reality II

Widespread Augmented Reality I will continue to use the old Google Maps for phones that do not have Google Play Services installed.

Android Studio Not Starting - Fixed

See previous post of a few days back.

Finally got Android Studio to start consistently, and I debugged the app Widespread Augmented Reality to a Galaxy Tab 2 7 inch tablet.

These are the steps after a fresh installation of Android Studio and Java on an Acer Windows 10 tablet 8 inch 1 GB RAM 32 bit.

File | Settings | Build Tools | Gradle > Check Use default gradle wrapper

....Build Tools | Compiler | Check Use in-process build; Check Configure on demand.

File | Other Settings | Default Settings | Build Tools | Compiler > Build process heap size (MBytes) : 2048

....Compiler | Android Compilers > Maximum heap size (MB) : 700MB (Note that this could be increased to 2048)

Create a gradle.properties in the parent directory and type 2 lines:

org.gradle.jvmargs=-Xmx1024M

org.gradle.daemon=true

Search on Windows for Environment variables and specify the path for JAVA_HOME

Navigate to your Android Studio program folder, e.g. c:/Program Files/Android/Android Studio/bin.

Edit or verify .../bin/studio.exe.vmoptions. In my case, I set -Xms512, -Xmx1024 -XX:MaxPermSize=300M

Back to Android Studio project and edit the Android.manifest file.

<uses-sdk android:minSdkVersion="15" android:targetSdkVersion="24" />
<application android:label="W.A.R. II" android:icon="@drawable/war4" android:name="android.support.multidex.MultiDexApplication">

Finally edit build.gradle (Module app).

android {
...
dexOptions {
incremental = true;
javaMaxHeapSize "1g"
}

Android Studio Not Starting

This is the first post of many to come documenting my progress on upgrading the app Widespread Augmented Reality.

Now that I am the number 45 Travel and Local app in Pakistan with a combined 20K+ downloads worldwide, I am upgrading from Google Maps API v1 to v2. Long time coming, but why fix it if it's not broken? But alas, members of the W.A.R. party deserve better.

First, a little history.

2012 - Developed with Eclipse on an Acer Netbook, 1GB RAM.

2015 - Migrated to Android Studio on an Acer Tablet, 2GB RAM.

2016 - Somehow broke my Android Studio installation while adjusting settings to work around heap size.

Determined that JAVA_HOME in environment variables is still correct, but Android Studio still not starting. Here is what I did to correct that.

Delete everything having to do with Android Studio, except my projects.
