get launchable activity name of package from adb

Question

Is there a way to get the launchable activity for a package from using adb? For an unroot phone (i.e. without having the pull the apk from /data/app directory and inspect with appt).

I tried dumpsys, but it does not include information on default launchable activity.

Thanks

Answer 1

#!/bin/bash
#file getActivity.sh
package_name=$1
#launch app by package name
adb shell monkey -p ${package_name} -c android.intent.category.LAUNCHER 1;
sleep 1;
#get Activity name
adb shell logcat -d | grep 'START u0' | tail -n 1 | sed 's/.*cmp=\(.*\)} .*/\1/g'

---

sample:

getActivity.sh com.tencent.mm
com.tencent.mm/.ui.LauncherUI

I didn't find it listed so updating the list.

You need to have the apk installed and running in front on your phone for this solution:

Windows CMD line:

adb shell dumpsys window windows | findstr <any unique string from your pkg Name>

Linux Terminal:

adb shell dumpsys window windows | grep -i <any unique string from your Pkg Name>

OUTPUT for Calculator package would be:

Window #7 Window{39ced4b1 u0 com.android.calculator2/com.android.calculator2.Calculator}:

    mOwnerUid=10036 mShowToOwnerOnly=true package=com.android.calculator2 appop=NONE

    mToken=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

    mRootToken=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

    mAppToken=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

    WindowStateAnimator{3e160d22 com.android.calculator2/com.android.calculator2.Calculator}:

      mSurface=Surface(name=com.android.calculator2/com.android.calculator2.Calculator)

  mCurrentFocus=Window{39ced4b1 u0 com.android.calculator2/com.android.calculator2.Calculator}

  mFocusedApp=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

Main part is, First Line:

Window #7 Window{39ced4b1 u0 com.android.calculator2/com.android.calculator2.Calculator}:

First part of the output is package name:

com.android.calculator2

Second Part of output (which is after /) can be two things, in our case its:

com.android.calculator2.Calculator

1. <PKg name>.<activity name> = <com.android.calculator2>.<Calculator>

   so .Calculator is our activity

2. If second part is entirely different from Package name and doesn't seem to contain pkg name which was before / in out output, then entire second part can be used as main activity.

Here is another way to find out apps package name and launcher activity.

Step1: Start "adb logcat" in command prompt.

Step2: Open the app (either in emulator or real device)

Answer 4

You don't need root to pull the apk files from /data/app. Sure, you might not have permissions to list the contents of that directory, but you can find the file locations of APKs with:

adb shell pm list packages -f

Then you can use adb pull:

adb pull <APK path from previous command>

and then aapt to get the information you want:

aapt dump badging <pulledfile.apk>

Answer 5

Since Android 7.0 you can use adb shell cmd package resolve-activity command to get the default activity of an installed app like this:

adb shell "cmd package resolve-activity --brief com.google.android.calculator | tail -n 1"
com.google.android.calculator/com.android.calculator2.Calculator

Answer 6

$ adb shell pm dump PACKAGE_NAME | grep -A 1 MAIN
