I found out you can only share either Text or Image, not both using Intents. Below code shares only Image if exists, or only Text if Image does not exits. If you want to share both, you need to use Facebook SDK from here.
If you use other solution instead of below code, don't forget to specify package name com.facebook.lite as well, which is package name of Facebook Lite. I haven't test but com.facebook.orca is package name of Facebook Messenger if you want to target that too.
You can add more methods for sharing with WhatsApp, Twitter ...
public class IntentShareHelper {
/**
* <b>Beware,</b> this shares only image if exists, or only text if image does not exits. Can't share both
*/
public static void shareOnFacebook(AppCompatActivity appCompatActivity, String textBody, Uri fileUri) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT,!TextUtils.isEmpty(textBody) ? textBody : "");
if (fileUri != null) {
intent.putExtra(Intent.EXTRA_STREAM, fileUri);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.setType("image/*");
}
boolean facebookAppFound = false;
List<ResolveInfo> matches = appCompatActivity.getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
for (ResolveInfo info : matches) {
if (info.activityInfo.packageName.toLowerCase().startsWith("com.facebook.katana") ||
info.activityInfo.packageName.toLowerCase().startsWith("com.facebook.lite")) {
intent.setPackage(info.activityInfo.packageName);
facebookAppFound = true;
break;
}
}
if (facebookAppFound) {
appCompatActivity.startActivity(intent);
} else {
showWarningDialog(appCompatActivity, appCompatActivity.getString(R.string.error_activity_not_found));
}
}
public static void shareOnWhatsapp(AppCompatActivity appCompatActivity, String textBody, Uri fileUri){...}
private static void showWarningDialog(Context context, String message) {
new AlertDialog.Builder(context)
.setMessage(message)
.setNegativeButton(context.getString(R.string.close), new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
})
.setCancelable(true)
.create().show();
}
}
For getting Uri from File, use below class:
public class UtilityFile {
public static @Nullable Uri getUriFromFile(Context context, @Nullable File file) {
if (file == null)
return null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
try {
return FileProvider.getUriForFile(context, "com.my.package.fileprovider", file);
} catch (Exception e) {
e.printStackTrace();
return null;
}
} else {
return Uri.fromFile(file);
}
}
// Returns the URI path to the Bitmap displayed in specified ImageView
public static Uri getLocalBitmapUri(Context context, ImageView imageView) {
Drawable drawable = imageView.getDrawable();
Bitmap bmp = null;
if (drawable instanceof BitmapDrawable) {
bmp = ((BitmapDrawable) imageView.getDrawable()).getBitmap();
} else {
return null;
}
// Store image to default external storage directory
Uri bmpUri = null;
try {
// Use methods on Context to access package-specific directories on external storage.
// This way, you don't need to request external read/write permission.
File file = new File(context.getExternalFilesDir(Environment.DIRECTORY_PICTURES), "share_image_" + System.currentTimeMillis() + ".png");
FileOutputStream out = new FileOutputStream(file);
bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
out.close();
bmpUri = getUriFromFile(context, file);
} catch (IOException e) {
e.printStackTrace();
}
return bmpUri;
}
}
