with revoked permission android.permission.CAMERA

1,剛出現這樣的問題我是直接把 CAMERA 移除掉

2.第一步判斷時候授權。

if (Build.VERSION.SDK_INT >= 23) {
 int checkCallPhonePermission = ContextCompat.checkSelfPermission(AppointmentDetailActivity.this, Manifest.permission.CAMERA);
 if(checkCallPhonePermission != PackageManager.PERMISSION_GRANTED){
 ActivityCompat.requestPermissions(AppointmentDetailActivity.this,new String[]{Manifest.permission.CAMERA},OPEN_CANMER);
 return;
 }else{
 showCamera();
 }
} else {
 showCamera();
}

第二步 接收返回的結果。

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
 switch (requestCode) {
 case OPEN_CANMER:
 if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
 showCamera();
 } else {
 Toast.makeText(AppointmentDetailActivity.this, "相機權限禁用了。請務必開啟相機權", Toast.LENGTH_SHORT).show();
 }
 break;
 default:
 super.onRequestPermissionsResult(requestCode, permissions, grantResults);
 }
}
