I am creating an app which uses REST API, for this I am using Okhttp API by square, and I am facing a challenge.
Earlier I was getting below error
E/WindowManager: android.view.WindowLeaked: Activity com.example.pawadube.helloworld.MainActivity has leaked window DecorView@3cc4f3[Connecting] that was originally added here
at android.view.ViewRootImpl.<init>(ViewRootImpl.java:417)
at android.view.WindowManagerGlobal.addView(WindowManagerGlobal.java:331)
By referring this question, I added the code in the onDestroy method to point the progress dialog. And now I get below error
E/AndroidRuntime: FATAL EXCEPTION: AsyncTask #4
Process: com.example.pawadube.helloworld, PID: 31149

at android.os.AsyncTask$2.call(AsyncTask.java:304)
On the button click I have added below code
new LoginServerTest().execute(username, password, url);
class LoginServerTest extends AsyncTask<String, Integer, String[]> {
@Override
protected void onPreExecute() {
super.onPreExecute();
progressDoalog.show();
}
@Override
protected void onPostExecute(String[] strings) {
super.onPostExecute(strings);
progressDoalog.dismiss();
}
@Override
protected String[] doInBackground(String... strings) {
String username = strings[0];
String password = strings[1];
String url = strings[2];
Log.d("Username: ", username);
Log.d("Password: ", password);
Log.d("URL--> ", url);
String credential = Credentials.basic(username, password);
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url(url)
.get()
.addHeader("authorization", credential)
.addHeader("content-type", "application/json")
.build();
try {
Response response = client.newCall(request).execute();
if (response.isSuccessful()) {
String body = response.body().string();
String code = response.code() + "";
String[] output = {code, body};
Toast.makeText(MainActivity.this, "Username/Password is correct." + response.body().string(), Toast.LENGTH_LONG).show();
Log.d("Responce-->", response.body().string());
return output;
} else {
Toast.makeText(MainActivity.this, "Username/Password is correct.", Toast.LENGTH_LONG).show();
Log.d("Responce-->", response.body().string());
return null;
}
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}
Please help me, I'm stuck.
