[JAVA] Add the pre-built jar library to Android and call it in the framework
What to do
- Create a test jar library and add the jar library to AOSP
- Call the API of the library added in 1 from within the framework (quick setting panel)
- Add an AWS library and try calling it from within the framework
1. Create test jar library
Create a jar library that implements a simple API that returns the test string "test".
Test.java
package com.testlib;
public class Test {
public String getTestString() {
return "test";
}
}
--Jar creation
$ javac Test.java
$ jar -cvf test-lib.jar *.class
Copy the jar created above to the AOSP source below
/prebuilts/misc/common/test-lib/test-lib.jar
Also create Android.mk
/prebuilts/misc/common/test-lib/Android.mk
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := optional
LOCAL_PREBUILT_JAVA_LIBRARIES := test-lib$(COMMON_JAVA_PACKAGE_SUFFIX)
include $(BUILD_HOST_PREBUILT)
2. Call the API of the library added in 1 from the quick setting panel
2-1. Source modification
When tapping the tile of the quick setting panel added appropriately, modify the AOSP source so that the character string "test" obtained from the above API is displayed in Toast.
/frameworks/base/packages/SystemUI/src/com/android/systemui/qs/tiles/LoggingTile.java
+import android.widget.Toast;
...
+import com.testlib.Test;
...
@Override
protected void handleClick() {
+ Test test = new Test();
+ Toast.makeText(mContext , test.getTestString(), Toast.LENGTH_SHORT).show();
try {
/frameworks/base/packages/SystemUI/Android.mk
...
LOCAL_STATIC_JAVA_LIBRARIES := \
SystemUI-tags \
SystemUI-proto
LOCAL_STATIC_JAVA_LIBRARIES += test-lib
...
include $(BUILD_PACKAGE)
+include $(CLEAR_VARS)
+LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := test-lib:../../../../prebuilts/misc/common/test-lib/test-+lib.jar#libs/test_lib/test-lib.jar
+include $(BUILD_MULTI_PREBUILT)
include $(call all-makefiles-under,$(LOCAL_PATH))
...
2-2. Build
--Build
$ make -j4
--System UI replacement
$ adb remount
$ adb push out/target/product/bullhead/system/priv-app/SystemUI /system/priv-app/
$ adb reboot
2-3. Operation check
Try tapping the tile
You can confirm that the API of the added library is called normally.
3. Add an AWS library and try calling it from within the framework
3-1. Library preparation
AWS SDK for Android
- aws-android-sdk-core.jar
- aws-android-sdk-lambda.jar
- aws-android-sdk-s3.jar
- aws-android-sdk-ddb.jar
- aws-android-sdk-ddb-mapper.jar
- aws-android-sdk-cognito.jar
Is copied under / prebuilts / misc / common / aws.
I got an error if Gson was not found, so copy the Gson jar to / prebuilts / misc / common / gson as well.
3-2. Try using Lambda
Similarly, modify it so that Lambda is called when the tile is tapped.
Official reference https://docs.aws.amazon.com/ja_jp/lambda/latest/dg/with-android-example.html https://docs.aws.amazon.com/ja_jp/aws-mobile/latest/developerguide/how-to-android-lambda.html
Source modification difference
3-3. Send a bug report to S3
You can get the bug report from the settings, but like the above, insert a wire so that you can get the bug report when you tap the tile.
packages/SystemUI/src/com/android/systemui/qs/tiles/LoggingTile.java
+ private Handler mHandler = new Handler();
...
@Override
protected void handleClick() {
+ mHandler.postDelayed(new Runnable() {
+ @Override
+ public void run() {
+ try {
+ ActivityManager.getService().requestBugReport(
+ ActivityManager.BUGREPORT_OPTION_INTERACTIVE
+ );
+ } catch (RemoteException e) {
+ Log.e(TAG, "requestBugReport() failed");
+ }
+ }
+ }, 500);
try {
Also, since the following will be called when the bug report acquisition is completed, add the process to save the bug report in S3 below.
frameworks/base/packages/Shell/src/com/android/shell/BugreportProgressService.java#onBugreportFinished
frameworks/base/packages/Shell/src/com/android/shell/BugreportProgressService.java
private void onBugreportFinished(int id, Intent intent) {
final File bugreportFile = getFileExtra(intent, EXTRA_BUGREPORT);
if (bugreportFile == null) {
// Should never happen, dumpstate always set the file.
Log.wtf(TAG, "Missing " + EXTRA_BUGREPORT + " on intent " + intent);
return;
}
+
+ try {
+ final String S3_ACCESS_KEY = "YOUR_ACCESS_KEY";
+ final String S3_SECRET_KEY = "YOUR_SECRET_KEY";
+ AmazonS3Client S3Client = new AmazonS3Client(
+ new BasicAWSCredentials(S3_ACCESS_KEY, S3_SECRET_KEY)
+ );
+ final String BUCKET_NAME = "aosp_test";
+ PutObjectRequest por = new PutObjectRequest(
+ BUCKET_NAME,
+ bugreportFile.getName(),
+ bugreportFile
+ );
+ S3Client.putObject(por);
+ } catch (final Exception e) {
+ Log.e(TAG, "Failed to save bugreport to S3", e);
+ }
mInfoDialog.onBugreportFinished();
BugreportInfo info = getInfo(id);
Source modification difference
Replace with build
$ make -j4
$ adb remount
$ adb push out/target/product/bullhead/system/priv-app/SystemUI /system/priv-app/
$ adb push out/target/product/bullhead/system/priv-app/Shell /system/priv-app/
$ adb reboot
Try tapping the tile.
You can see that it is saved in S3.
3-4. Try saving records in DynamoDB
Source modification difference
After tapping the tile, you can confirm that the record is saved in DynamoDB ↓
Note
Error 1
SystemUI sometimes crashed due to Fatal Exception such as permission android.permission.READ_CONTACTS after startup, but it was solved by simply FDR.

-keep class com.android.systemui.qs.tiles.AOSPTest { *; }
