Android-在默认库应用程序中从可绘制对象打开图像

Question

I'm working on app that have number of imageviews, when i click on the image i want it to open via android default gallery image picker. i've tried in this way :

String str = "android.resource://" + getPackageName() +"/"+R.drawable.wall1;

Uri path = Uri.parse(str);
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(path, "image/*");
startActivity(intent);

but it doesn't work and i get exception: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=android.resource://com.example.demo/2130837505 typ=image/* }

Answer 1

That is because there is no activity on your device capable of viewing an image residing at a Uri with the android:resource:// scheme. If I had to guess, ~99% of Android devices will have a similar problem.

Either write your own image viewer, or move the image someplace that third-party apps are more likely to support, such as your own ContentProvider or a local file.
