I’ve had this problem myself, the reason is that when APK files are included in a build they are essentially bypassing the installation process. This installation process is the point at which any shared libraries are extracted from the apk and put in the appropriate place, ergo if that never happens the libraries will not … Read more
The reason why it works when installed as a third party application, is that on installation, the package manager scans the APK and checks if it uses native libraries, and if such are found, it stores which ABI they used (since it only installs libraries for one single ABI, so the info about which choice … Read more
So after some digging, it’s clear that apps in priv-app are eligible for system permissions, the same way that old apps used to be eligible to claim system permissions by being in system-app. The only official Google documentation I could find on this came in the form of a commit message: Commit hash: ccbf84f44c9e6a5ed3c08673614826bb237afc54 Some … Read more

Adding a new APK to the build In the AOSP root add the folder: <aosp root>/package/app/< yourappfolder > Then inside this folder add: empty Android.mk < yourapp.apk > The android … Read more
Do an actual full checkout of the source according to Google’s directions. As of Android 4.2, the keyguard source is at frameworks/base/policy/src/com/android/internal/policy/impl/keyguard. There’s a mirror on GitHub you can look at online (I pegged this link to the JB MR 1.1 release in case the location changes again in a future release). When this question … Read more

Everything is mirrored on omapzoom.org. Some of the code is also mirrored on github. Contacts is here for example. Since December 2019, you can use the new official public code search tool for AOSP: cs.android.com. There’s also the Android official source browser (based on Gitiles) has a web view of many of the different parts … Read more
This is what I always do to use hidden api. Build the repo or download jars from https://sites.google.com/site/hippunosource/home/android/androidnohide-apiwo-shi-yongsuru-rifurekushonha-wei-shi-yong copy out out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/classes.jar (better to rename it as something like framework_all.jar) config your project build path–>libraries –> add this external jars. In Order and Export, move it up and before android.jar
If you use the “reflection” option, you may use the class below package com.etc.etc; import java.io.File; import java.lang.reflect.Method; import android.content.Context; import dalvik.system.DexFile; public class SystemPropertiesProxy { /** * This class cannot be instantiated */ private SystemPropertiesProxy(){ } /** * Get the value for the given key. * @return an empty string if the key isn’t … Read more
