Android: Comment utiliser grantUriPermission pour être en mesure de créer et d'envoyer un e-mail avec une image de la pièce jointe

J'ai eu un problème similaire. Ci-dessous comment j'ai résolu le problème pour mon projet. Vous devriez être en mesure d'adapter votre solution. Cette solution a aussi quelques Firebase code, que vous pouvez ignorer. Les points clés sont ActivityCompat.requestPermissions et ActivityCompat.checkSelfPermission:

private void shareViaEmail() {
int permissionCheck = ContextCompat.checkSelfPermission(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
AlertDialog.Builder alertBuilder = new AlertDialog.Builder(this);
LayoutInflater inflater = this.getLayoutInflater();
final ViewGroup nullParent = null;
final View dialogView = inflater.inflate(R.layout.alert_dialog, nullParent);
alertBuilder.setView(dialogView);
alertBuilder.setCancelable(true);
alertBuilder.setTitle("Permission request");
String message = "\n\n" + getString(R.string.email_images);
AppCompatTextView notice = (AppCompatTextView) dialogView.findViewById(R.id.notice);
if (notice != null) {
notice.setText(message);
notice.setTextSize(getResources().getInteger(R.integer.dialog_text_size));
}
else {
alertBuilder.setMessage(message);
}
alertBuilder.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
public void onClick(DialogInterface dialog, int which) {
mShowingAlert = false;
ActivityCompat.requestPermissions(baseActivity(), new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, MY_TARGET_WRITE_PERMISSION_REQUEST);
}
});
mAlertDialog = alertBuilder.create();
mAlertDialog.show();
return;
}
}
ActivityCompat.requestPermissions(this,
new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE},
MY_TARGET_WRITE_PERMISSION_REQUEST);
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
if (requestCode == MY_TARGET_WRITE_PERMISSION_REQUEST) {
doShareViaEmail();
} else {
failWriteImage();
}
}
}
protected void failWriteImage() {
getHandler().post(new Runnable() {
@Override
public void run() {
String email_failed = getResources().getString(R.string.fail_email_attach);
@SuppressLint("ShowToast") Toast toast = Toast.makeText(getApplicationContext(), email_failed, Toast.LENGTH_SHORT);
new CustomToast(toast).invoke();
}
});
}
protected void doShareViaEmail() {
FireUtilities fireUtilities = FireUtilities.getInstance();
fireUtilities.logEvent(mFirebaseAnalytics, "option_item", "share", "share_string");
Intent intent = new Intent(Intent.ACTION_SEND_MULTIPLE);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra(Intent.EXTRA_SUBJECT, getString(R.string.string_share));
String appStoreLink = getString(R.string.app_store_link);
String emailText = getString(R.string.share_string_body1)
+ " " + appStoreLink
+ " " + getString(R.string.share_string_body2);
emailText = emailText + "<br><br>" + getTitleOfSegment(true, mCurrentSegment, mCurrentSegmentIndex);
Bitmap targetImage = screenShot(mTargetImageView);
if (targetImage != null) {
ArrayList<Uri> files = new ArrayList<Uri>();
String path = MediaStore.Images.Media.insertImage(getContentResolver(), targetImage, "string", null);
Uri targetUri = Uri.parse(path);
files.add(targetUri);
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, files);
}
intent.setType("message/rfc822");
Spanned htmlText = fromHtml(getString(R.string.share_score_head1)
+ emailText + getString(R.string.share_score_head2));
intent.putExtra(Intent.EXTRA_TEXT, htmlText);
try {
startActivityForResult(Intent.createChooser(intent, "Email:"), 1234);
} catch (final android.content.ActivityNotFoundException e) {
String no_email_client = getResources().getString(R.string.no_email_client);
@SuppressLint("ShowToast") Toast toast = Toast.makeText(getApplicationContext(), no_email_client, Toast.LENGTH_LONG);
new CustomToast(toast).invoke();
}
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1234) {
LogHelper.v(TAG, "e-mail successfully sent");
}
}
public Bitmap screenShot(View view) {
if (view != null) {
Bitmap bitmap = Bitmap.createBitmap(view.getWidth(),
view.getHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
view.draw(canvas);
return bitmap;
}
return null;
