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!!!

Add this line in the proguard config file fixes the issue for me.

Android Studio Weather Application Crashing

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:

(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);

Android Studio Loading Texture error

I have this strange error where I can't load any textures anymore. The assets that I used are fine, but when I try to add new assets, it throws me this:

I didn't do anything stupid. I also tried to trick him and put the new texture with the name of an old one and it didn't work. This is the first time this happens, I have thousands of lines in the code.

The problem was with the bit depth. It needs to be smaller.

getResources returns null

We register a broadcast receiver to receive package installment or uninstallment event.
But some users report crash reports like this:

It is not easy to reappear this crash. We think a lot about this problem. We receive a
uninstall event ,then the Application context Class called it's onCreate method, we do
some initial works there , when we call getResouce(), it returns null . When look deep
inside the framework codes, we find that getReource locate resources file by sourceDir
String in ApplicationInfo, and the String is "/data/app/com.cm.mg-1.apk" > it's the original apk , and it is not exists anymore.
It maybe happens when user update our application. In some way "/data/app/com.cm.mg-1.apk" is allready deleted and replace by "/data/app/com.cm.mg-2.apk" any way, but the "sourceDir" String in ApplicationInfo is not update.
I want to know what android does when doing a updating.

Encountered a similar problem, check this out.
RuntimeException: Unable to instantiate application
I think this should answer this question, maybe because the Resources has been destroyed during this uninstall event.
