Leak comes because you are keeping reference of activity after it destroyed also so use
泄漏是因为您在活动销毁后仍保留对活动的引用，因此请使用
if(progressDialog !=null)
{
progressDialog = null;
}
progressDialog = new ProgressDialog(this.getApplicationContext());
progressDialog.setMessage("Uploading data, please wait...");
OR
或者
use this it will help
使用它会有所帮助
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btnSubmitNow:
// Submit now
// Sample upload image
UploadImage.uploadImage("testimage");
new AsyncTask<Void, Void, Void>() {
// called before execution // main/UI thread
protected void onPreExecute() {
progressDialog = new ProgressDialog(SignOut_Activity.this);
progressDialog.setMessage("Uploading data, please wait...");
progressDialog.show();
};
@Override
protected Void doInBackground(Void... params) {
// Submit the store data
StoreData.postData(StoreList_Activity.storesList
.get(StoresListAdapter.Position));
return null;
}
// on store data uploaded // main/UI thread
protected void onPostExecute(Void result) {
progressDialog.dismiss();
setSignOut();
StoreList_Activity.storesList
.get(StoresListAdapter.Position).isSubmitted = true;
SignOut_Activity.this.finish();
};
}.execute();

Dismiss the dialogafter its use, it won't let your application crash.
dialog使用后关闭它，它不会让您的应用程序崩溃。
dialog.dismiss();
回答by Harsh Dattani
Make sure you dismiss() the dialog, after dialog use and before any next background process to be initiated.
确保在使用对话框之后和启动任何下一个后台进程之前关闭（）对话框。

remove reference of progress bar , dialog .....etc after use it .
使用后删除进度条、对话框.....等的引用。

当不再需要它时，您可以使用它
Recommendedput it in onStop
建议把它放在onStop
@Override
protected void onStop() {
super.onStop();
if(_dialog.isShowing()){
_dialog.dismiss();
}
if(_dialog != null){
_dialog = null;
}
}
