when the application instance taking picture the first time it works fine, but in the second time it throws me this error.
I'm using LGE LM-K520 device android 11.
this is the code:
findViewById(R.id.pic).setOnClickListener((a) -> takePicture());
this is my config:
mCameraConfig = new CameraConfig()
.getBuilder(MainActivity.this)
.setCameraFacing(CameraFacing.REAR_FACING_CAMERA)
.setCameraResolution(CameraResolution.HIGH_RESOLUTION)
.setImageFormat(CameraImageFormat.FORMAT_JPEG)
.setImageRotation(CameraRotation.ROTATION_90)
.build();
Thank You!!!

I have an android app that has a second module included in the app when the main activity starts an activity in the module everything is good. The problem is if you go to another app and then resume this app the activity crashes with a null object pointer. My app uses Esri ArcGIS runtime SDK. I have a MapView open in the activity when the crash occurs. I don't have any problem with an open map in the MainActivity and the app goes to the background then back to the current app.

I systematically went through my onCreate() method and added each piece of the code to find where the problem was. I found some code that was suspicious and I could not recall why I added the code. With the code removed the app works fine.
I want to add Internet Connection Problem Dialog in my Async Task subclass. I tried many methods but the same error happened when my internet not connected.

Please comment If you want any other information.
You are casting data into inputStream, if you want to create this object you should do something like : ByteArrayInputStream( data.getBytes() )
probably you should post your onExecute too to see what are you trying to do
So, I have been following a YouTube tutorial for an android Weather application. The app seems to compile, however crashes whenever opened on the emulator. I'm not the most fluent programmer, however the code is understood. I can't figure out what's causing the issue though. The app is supposed to fetch weather data for the location of the hardcoded location in "MainActivity.java". The data is fetched from Yahoo! using an API.
Link for the project files: https://drive.google.com/drive/folders/0B2dQ9-JQjysVeXlqZENBZDExN0E?usp=sharing
Below is the error I get:
--------- beginning of crash

(Sorry, I am new to this site!)
Any help is greatly appreciated.
As StackTrace says the error is at Class WeatherService at line 81 int count = queryResults.optInt("Count"); because it is returning NULL.
Try using method optInt with fallback value queryResults.optInt("Count", 0);
I am using Amazon S3 Cloud storage to my application which is working fine but still the Crash logging tool showing the crashes for TransferService.java
here are my implementation details :
1) Dependencies:
compile 'com.amazonaws:aws-android-sdk-core:2.3.6'
compile 'com.amazonaws:aws-android-sdk-cognito:2.3.6'
compile 'com.amazonaws:aws-android-sdk-s3:2.3.6'
2) Create S3 client:
public static AmazonS3Client getAWS3Client() {
if (s3Client == null) {
CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(
AppDeligate.getInstance(),
Credentials.IDENTITY_POOL_ID, // Identity Pool ID
Credentials.REGION // Region
);
return s3Client = new AmazonS3Client(credentialsProvider);
}
return s3Client;
}
3) Create object of TransferUtility:
TransferUtility transferUtility = new TransferUtility(AppDeligate.getAWS3Client(), mContext);
4) Complete Crashlog:

A debug hint to get you going:
See if you can get access to the TransferService source code (starting point could be here
Check what this code is doing on line 172; and if you can relate that to anything your code is doing upfront
One can easily find the way to TransferService ... but it looks like this is a newer version; as line 172 is empty.
But I think my idea could give you something to get going.
I get the error Fatal Exception main whenever I run application .
the app uses opencv 2.4.10 it has worked on one device and it fails on my device I couldn't figure out why this is happening.
I don't know which part is code is causing this error :

please any solution would be very thankful.
Apparently there is a task running which is using the context here with OpenCBLoader
(!OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_3, this, mLoaderCallback))
The problem related with context i.e the context is not valid anymore
.Try passing getApplicationContext() instead of this
(!OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_3, getApplicationContext(), mLoaderCallback))
Consider a case when AMK(android memory killer) kill your service due to memory shortage because service get to destroyed first before foreground activity and now your service is dead, plus the this context is not valid anymore hence Exception
