using ``NotificationCompat`` in ``support-v4`` library will increase APK filesize a little bit, but it guarantees to run OK with API 4+
tested with API 19 and 23 devices
If we update build gradle to use ``compileSdkVersion 23``,
``org.apache.http`` package causes error. (issue #4711)
We need to use ``useLibrary 'org.apache.http.legacy'`` to solve this problem.
To use ``useLibrary``, we need to use latest gradle also.
And now, we faced another problem with ``APK Expansion`` java sources.
```
/platform/android/java/src/com/google/android/vending/expansion/downloader/impl/DownloadNotification.java
137 : mCurrentNotification.setLatestEventInfo(mContext, mCurrentTitle, mCurrentText, mContentIntent); // causes error
```
So, some of APK Expansion java sources are updated by referencing commits from https://github.com/danikula/Google-Play-Expansion-File
And dropped V3CustomNotification.java which was for android 3.0, since godot supports android 14 (4.0) above officially.
Unfortunately, another problem, The 'MissingTranslation' error was occurred.
So, build.gradle is updated to use ``disable 'MissingTranslation'``
Additionally, I updated ``buildToolsVersion``, ``targetSdkVersion`` to latest version.
I tested APK Expansion funtionality on Android 6.0 (Nexus 9, Nexus 6p) and Android 4.4 (Galaxy Note 2) with Google Developer console.
It was added in 30d0ca9 for the Steam build but only enabled
when parsing a ._sc_ file that would define it.
It is now available for all users to toggle, in and outside of Steam.
Fixes#4073.
The 4.9 version is the default one, people can still build using 4.8
with older NDK versions by setting the (optional) NDK_TARGET
and NDK_TARGET_X86 environment variables.
Useful for everybody wanting to package godot.
Fixes#1026.
-> Retain the old behaviour: path in error msg only when exporting.
-> User templates override system templates
add version_info and icon sections in "export to windows platform".
add version_info and icon to godot exe file (editor & template exe).
fix an problem in image class.
change all default icons to android export icon (a little more rounded).
create an python script for convert file to cpp byte array for use in
'splash.h'.
