当我从图库中选择视频时，会出现安全类型异常。但是除了4.3版本之外，同样的代码在所有Android版本中都可以正常工作。我搜索了答案，有人建议在activity部分使用android:exported="true"。但是我仍然遇到了相同的异常。
我的代码如下：
@Override
public void onClick(View v) {
if(btngetvideo==v)
{
Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Video.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, 1); //<-- Here m getting exception
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode,
Intent resultData) {
super.onActivityResult(requestCode, resultCode, resultData);
Log.v(TAG + ".onActivityResult", "onActivityResult call");
try {
if ( resultData != null) {
String[] projection = { MediaStore.Video.Media.DATA };
@SuppressWarnings("deprecation")
Cursor cursor = managedQuery(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,
projection, null, null, null);
int column_index_data = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA);
cursor.moveToLast();
videopath= cursor.getString(column_index_data);
messageText.setText("Uploading file path :"+ videopath);
dialog = ProgressDialog.show(MainActivity.this, "", "Uploading file...", true);
new Thread(new Runnable() {
public void run() {
runOnUiThread(new Runnable() {
public void run() {
messageText.setText("uploading started.....");
}
});
uploadFile(videopath);
//uploadFile(path);
}
}).start();
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
和清单代码：
