我有一个应用程序应该使用
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("image/jpg");
shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file) );
shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Created in x");
shareIntent.putExtra(Intent.EXTRA_TEXT, "Created in x");
shareIntent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
context.startActivity(Intent.createChooser(shareIntent, "Share via..."));
适用于 gmail 和其他选项，但当我尝试通过 FOURSQUARE 共享它时会崩溃。
