According to you log
根据你的日志
Failure delivering result ResultInfo{who=null, request=1, result=-1, data=Intent { dat=content://media/external/images/media/39 }} to activity {com.holomedia.holomedia/com.holomedia.holomedia.Add_video}: java.lang.SecurityException: Permission Denial: reading com.android.providers.media.MediaProvider uri content://media/external/images/media/39 from pid=5357, uid=10060
requires android.permission.READ_EXTERNAL_STORAGE, or grantUriPermission()
未能将结果 ResultInfo{who=null, request=1, result=-1, data=Intent { dat=content://media/external/images/media/39 }} 传递到活动 {com.holomedia.holomedia/com。 Holomedia.holomedia.Add_video}：java.lang.SecurityException：权限拒绝：从 pid=5357，uid=10060 读取 com.android.providers.media.MediaProvider uri content://media/external/images/media/39
需要 android.permission.READ_EXTERNAL_STORAGE 或 grantUriPermission()
Because when the app Android version is 6.0, you must require Runtime permission READ_EXTERNAL_STORAGE.
因为当app安卓版本是6.0的时候，必须需要Runtime权限READ_EXTERNAL_STORAGE。
You can do like this
你可以这样做
/**
* permission code
*/
private static final int MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE = 1;
/**
* requestPermissions and do something
*
*/
public void requestRead() {
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.READ_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);
} else {
readFile();
}
}
/**
* do you want to do
*/
public void readFile() {
// do something
}
/**
* onRequestPermissionsResult
*
* @param requestCode
* @param permissions
* @param grantResults
*/
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
if (requestCode == MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
readFile();
} else {
// Permission Denied
Toast.makeText(ToolbarActivity.this, "Permission Denied", Toast.LENGTH_SHORT).show();
}
return;
}
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
or
