I'm trying to write an app that sends SMS. When checking if I have the required permissions it returns true but still crashes with SecurityException.

When button is pressed

```
private void startAutoMsg() {
    Log.d("Starting Auto Msg");
    //FIXME: Start proper loop
    if (canSendSms()) {
        sendMessage();
        mAutoMsgButton.setBackgroundColor(Color.GREEN);
    }
}

```

I'm using the below function to determine if I have the proper permission

```
private boolean canSendSms() {
    if ((ContextCompat.checkSelfPermission(mContext, Manifest.permission.SEND_SMS)
            == PackageManager.PERMISSION_GRANTED)) {
        Log.d("Permission granted");
        return true;
    } else {
        Log.d("Permission denied");
        ActivityCompat.requestPermissions(
                mActivity, new String[]{Manifest.permission.SEND_SMS}, 101);
        return false;
    }
}

```

The above code returns true and therefore SMS is trying to be sent with this

```
private void sendMessage() {
    Log.d("sending message");
    PendingIntent sentPI = PendingIntent.getBroadcast(
            mContext, 0, new Intent(Constants.ACTION_SMS_SENT), 0);
    PendingIntent deliveredPI = PendingIntent.getBroadcast(
            mContext, 0, new Intent(Constants.ACTION_SMS_DELIVERED), 0);
    Thread thread = new Thread(new Runnable() {
        @Override
        public void run() {
            mSmsManager.sendTextMessage("mNumber", null, mText, sentPI, deliveredPI);
        }
    });
    thread.run();
}

```

In my manifest:

```
<uses-permission android:name="android.permission.SEND_SMS"/>
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.WRITE_SMS" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.RECEIVE_MMS" />

```

Log from crash
