在startrequest之后没有调用Android startactivityforresult

Question

OnActivityResult没有被调用，我想知道是不是因为我刚刚添加了一个权限请求（它之前工作正常）。下面是代码，它在请求许可后启动了startactivityforresult的意图。

    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
        Log.v("showEmails","build<");
        return true;
    }
    if (checkSelfPermission(READ_CONTACTS) == PackageManager.PERMISSION_GRANTED) {
        return true;
    }
    if (shouldShowRequestPermissionRationale(READ_CONTACTS)) {
        Snackbar.make(findViewById(android.R.id.content), "permission_rationale", Snackbar.LENGTH_INDEFINITE)
                .setAction(android.R.string.ok, new View.OnClickListener() {
                    @Override
                    @TargetApi(Build.VERSION_CODES.M)
                    public void onClick(View v) {
                        requestPermissions(new String[]{READ_CONTACTS}, REQUEST_READ_CONTACTS);
                    }
                });
    } else {
        requestPermissions(new String[]{Manifest.permission.READ_CONTACTS}, REQUEST_READ_CONTACTS);
        Log.v("showEmails","requestPermissions");
    }
    return false;
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
                                       @NonNull int[] grantResults) {
    if (requestCode == REQUEST_READ_CONTACTS) {
        if (grantResults.length == 1 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

    Uri imageUri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);
    if (imageUri != null) {
        ImageView ivShare = (ImageView) findViewById(R.id.ivShare);
        ivShare.setImageURI(imageUri);
        Intent emailIntent = new Intent(Intent.ACTION_SEND);
        emailIntent.setType("application/image");
        emailIntent.putExtra(Intent.EXTRA_TEXT, textIntent);
        emailIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
        emailIntent.setFlags(0);
        startActivityForResult(emailIntent, GMAILSENT);
    }
  }
}
