Android studio error unfortunately application has stopped

Unfortunately MyApp has stopped. How can I solve this?

I am developing an application, and everytime I run it, I get the message:

Unfortunately, MyApp has stopped.

What can I do to solve this?

About this question — obviously inspired by What is a stack trace, and how can I use it to debug my application errors?, there are lots of questions stating that their application has crashed, without any further detail. This question aims to instruct novice Android programmers on how to try and fix their problems themselves, or ask the right questions.

This answer describes the process of retrieving the stack trace. Already have the stack trace? Read up on stack traces in «What is a stack trace, and how can I use it to debug my application errors?»

The Problem

Your application quit because an uncaught RuntimeException was thrown.
The most common of these is the NullPointerException .

How to solve it?

Every time an Android application crashes (or any Java application for that matter), a Stack trace is written to the console (in this case, logcat). This stack trace contains vital information for solving your problem.

Android Studio

In the bottom bar of the window, click on the Logcat button. Alternatively, you can press alt + 6 . Make sure your emulator or device is selected in the Devices panel. Next, try to find the stack trace, which is shown in red. There may be a lot of stuff logged into logcat, so you may need to scroll a bit. An easy way to find the stack trace is to clear the logcat (using the recycle bin on the right), and let the app crash again.

I have found the stack trace, now what?

Yay! You’re halfway to solving your problem.
You only need to find out what exactly made your application crash, by analyzing the stack trace.

I still can’t solve my problem!

If you’ve found your Exception and the line where it occurred, and still cannot figure out how to fix it, don’t hesitate to ask a question on StackOverflow.

Try to be as concise as possible: post the stack trace, and the relevant code (e.g. a few lines up to the line which threw the Exception ).

You can use Google’s ADB tool to get Logcat file to analyze the issue.

open logcat.txt file and search for your application name. There should be information on why it failed, the line number, Class name, etc.

First, you check which point your app has crashed ( Unfortunately, MyApp has stopped. ). For this, you can use Log.e(«TAG», «Message»); , using this line you can see your app log in logcat.

After that, you find which point your app has stopped it’s very easy to solve at your side.

Just check the error in log cat.

You get the log cat option from in eclipse:

Log cat contains error.

Other wise you can also check the error by executing an application in debug mode. Firstly set breakpoint after that by doing:

right click on project->debug as->Android application

Note: This answer is using Android Studio 2.2.2

Note 2: I am considering that your device is successfully connected.

The first thing you do when your application crashes is look into the LogCat, at the bottom of Android Studio there’s a toolbar with a list of menus:

Click on the «Android Monitor» (The one I underlined in the image above. ^)

Now, you’ll get something like this:

Change » Verbose » to » Error » Now it will only show you logged errors. Don’t worry about all these errors (if you got them) now.

Ok. Now, do what you did to crash your app. After your app crashes, go to your logcat. You should find a new crash log that has a lot of at:x.x.x : and Caused by: TrumpIsPresidentException for example. Go to that Caused by: statement in your logcat.

Next to that Caused By: , there should be the Exception that happened. In my case, it’s a RuntimeException and under it there should be a line which contains a blue link such as:

If that Caused by: DOESN’T have a line with a blue text somewhere under it, then look for another Caused by: that does.

Click on that blue link. It should take you to where the problem occured. In my case, it was due to this line:

So, now I know why it’s crashing. It’s because I’m throwing the exception myself. This was an obvious error.

However, let’s say I got another error:

I checked my logcat, I clicked on the blue link it gave me, and it took me here:

So, now I want to debug. According to this StackOverflow question, a NullPointerException says that something is null .

So, let’s find out what is null. There’s two possibilities. Either mTextView is null, or myString is null. To find out, before the mTextView.setText(mString) line, I add these two lines:

Now, like we did previously (We changed Verose to Error), we want to change «Error» to «Debug». Since we’re logging by debugging. Here’s all the Log methods:

So, since we used Log.d , we’re checking in Debug. That’s why we changed it to debug.

Notice Log.d has a first parameter,in our case «AppDebug». Click on the «No Filters» drop down menu on the top-right of the logcat. Select «Edit Filter Configuration», give a name to your filter, and in «Log Tag» put «App Debug». Click «OK». Now, you should see two lines in the logcat:

So now we know that mTextView is null.

I observe my code, now I notice something.

I have private TextView mTextView declared at the top of my class. But, I’m not defining it.

Basically I forgot to do this in my onCreate():

So THAT’S why mTextView is null, because I forgot to tell my app what it is. So I add that line, run my app, and now the app doesn’t crash.

3: Factory Reset (OPTIONAL).

This is not the best solution, but if you have stuck on the critical issue, then I would like to go for factory reset.

Dear valuable reader one can go with this method unless you cannot clear the issue by moving with all the above-suggested methods. A factory reset wipes your phone’s internal memory clean and restores everything back to its default. So suggesting to do a backup before resetting.

Unfortunately, android has stopped — что делать

Система Андроид, несмотря на постоянные обновления и новые версии, все равно имеет множество багов. Тоже стоит сказать и про устанавливаемые приложения. Так, пользователи использующие англоязычные настройки Android или такие же программы, получают уведомления «Unfortunately, [приложение] has stopped». Сегодня мы расскажем что делать для решения подобных проблем в смартфоне.

Что это за сбой

По сути, это окно является сообщением о критической ошибке, из-за которой процесс был остановлен системой. Буквально, баг читается как — «К сожалению, этот процесс был завершен».

Ошибка «Unfortunately, the process com.android.phone has stopped»

Сам сбой может быть вызван многими причинами — устарелыми обновлений программы, перегруженной системой, битой прошивкой Андроида, вирусами, несоответствием поддерживаемых версий.

Что делать для исправления

Наиболее часто подобная проблема встречается в следующих процессах: com.android.settings, Google Play Services, com.android.phone, Setup Wizard, Launcher, System UI, Bluetooth. Например, мы уже писали про решение сбоев в com.android.settings и системной службе System UI. В любом случае, решения для всех подобных ошибок, практически одинаковые и потребуют нескольких действий.

Для начала, с указанным в ошибке приложением нужно сделать стандартное действие: стираем кэш, очищаем данные и останавливаем. Искать эти службы надо в Настройках — Диспетчер приложений — вкладка «Все».

Пример очистки данных

Откат системного приложения Google

Хорошим методом определения источника будет переход в безопасный режим. Такой режим запуска автоматически отключает все сторонние программы, если ошибка исчезнет, тогда поочередно сносите, либо переустанавливайте программки. Вот как войти в этот режим на Samsung.

Если ошибка останется даже в безопасном режиме, тогда вы имеете дело с проблемной ОС. В таком случае поможет сброс до заводских, либо прошивка устройства.

Заключение

Мы описали общие шаги, которые подскажут что следует делать в первую очередь со сбоем «Unfortunately, process has stopped». Подробнее в Рунете следует искать русскоязычные вариации «В приложении произошла ошибка» и «Процесс остановлен», добавив к ним сам источник бага.
