java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER]

Question

There is an error launching activity, unfortunately I assume it is not connected strictly with the project due to the fact the app launches on genymotion emulator, but does not on physical device.

When I run adb devices with the real one connected i get:

List of devices attached 
0009215b1eef4f  device

AndroidManifest.xml has not any permissions required set and device has sufficient api version.

This can also happen if you have added android:exported="false" in Manifest – Mosra

Answer 1

The issue was with Launcher selection in Android Studio. To improve testing speed of application module there was selected other Activity as Launcher(in run properties) than specified in manifest.xml. Strange that it worked even on emulator..

The solution is simply to change the Launcher to the one set in AndroidManifest.xml

Correct, running specified activity won't help if we want to test particular activity for no. of times ... instead using your solution and running app helps better :) thanks for hint! – Stroll

Answer 2

Simply add:

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

on AndroidManifest.xml into the tag:

<activity>

Hope it helps

Answer 3

As @Tushar Gogna said in the comment.

"This can also happen if you have added android:exported="false" in Manifest"

Adding this as the answer, since it worked for me.

Doable

Answer 4

For me the issue was with emulator. I added my company gmail to the emulator for testing and it forced me to setup pin. When I tried running the app the next day, I started getting this error.

Deleting the old and creating a new emulator was the solution that worked for me.
