Android-Activity-Tester

Enumerates all exported and non-exported activities, launches exported activities one by one using adb, and then non-exported activities as root.

According to the Android documentation, an activity is considered exported in the following two cases:

• If the activity declares the android:exported="true" attribute in its definition;
• If android:exported is not defined but the activity includes at least one intent-filter.

In order to use this tool, you need to specify the path to the app's AndroidManifest.xml file, as well as the package identifier:

~ python3 android_activity_tester.py \
  -m <path-to-decompiled-directory>/AndroidManifest.xml \
  -p <package-identifier>

Note that you can extract the manifest file from an APK using apktool, e.g.:

~ apktool d com.twitter.android.apk

[...]

~ python3 Android-Activity-Tester/android_activity_tester.py \
-m com.twitter.android/AndroidManifest.xml \
-p com.twitter.android
