Android 6.0上对requestPermissions的ActivityNotFoundException

Question

I get a crash at a user when calling requestPermissions on a samsung S5. I don't understand what could be the reason?

  if (Build.VERSION.SDK_INT >= M) {
       if(checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED)
            MainActivity.this.requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 100);

Here is the stack crash:

Caused by: android.content.ActivityNotFoundException: 
  at android.app.Instrumentation.checkStartActivityResult (Instrumentation.java:1878)
  at android.app.Instrumentation.execStartActivity (Instrumentation.java:1673)
  at android.app.Activity.startActivityForResult (Activity.java:4915)
  at android.app.Activity.requestPermissions (Activity.java:4167)
  at com.narb.checknetwork.MainActivity.permissionRequest (MainActivity.java:276)
  at com.bernard_zelmans.checknetwork.MainActivity.onCreate (MainActivity.java:101)

Added information.

I have all the permissions I require included.

Here is my manifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

</manifest>

Answer 1

used below code

if (Build.VERSION.SDK_INT >= M) {
        if(checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED)
            this.requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 100);
}

Answer 2

Try like below...

if (Build.VERSION.SDK_INT >= M) {
   if(checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED)
        ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 100);

One more important thing, Check whether you declared MainActivity in your Manifest.xml or not
