I just run into s problem.When I changed my gradle version to 2.1.0(old version is 1.5.0),my code went wrong.And it's wierd there is no logcat,so I just don't know how to find the problem and the wrong part code. I have tryed to add android:allowClearUserData="true" in my AndroidManifest .it turns out not working. when I change my gradle version to the old one,it goes well.I am a new coder,and I use Retrofit to do the network job.plz just help me.Oh and I open the OpenGL stack in the logcat,It will call glGetError() then it goes crush.
From your description, I have no idea. If only upgrading AS, it should be not crashed, but for possible updated SDK or Build tool Env. If you back to 1.5, even no crash when using same platform sdk, support library sdk?
After upgrading 2.1.0, When was crash happened? launching app, or opening some Activity? If later, you should limit your code to some extension, then searching from Google.
From crash info, it should be related with JNI. if you use JNI,your app has a library path in the app installed directory to list all support ABI .so. You could found the differ btw woking machine and abnormal one. From this stackOverflow, you can try too.

I have a Xamarin for Android app that has been working until today. I needed to make a change but before I did, I ran a test to ensure no VS or Nuget package updates caused an issue. I have Xamarin.Essentials in my app and this line worked before, not sure what is happening now.
if(DeviceInfo.Model == "TC72"){scannerIndex = 1;}
Exception Unhandled:
Xamarin.Essentials.NotImplementedInReferenceAssemblyException: 'This
functionality is not implemented in the portable version of this
assembly. You should reference the NuGet package from your main
application project in order to reference the platform-specific
implementation.'
Any insight would be helpful. TIA
I changed the DeviceInfo.Model to Build.Model and get the same info I was expecting. That fixed my issue. If anyone has a different suggestion, happy to entertain them.

I also found that changing my Compile Target to 10.0 fixed the Xamarin.Essentials issues. So far the application is working on 8.1 on the device (Zebra MC3300).
Im building ionic 3 (angular5+es2015) application for android OS, it's working for android 7,8, and 9 but not for 6 version, and i got this error when startup application :
Any help please !
I think the issue is that the Javascript VM in Android 6 is too old to have support for arrow functions. The solution would be to use a transpiler like Babel to target the older VM, or to rewrite your code to remove uses of ES6 language features.
Edit: I'm sorry, I realized that there is a "Typescript" tag on this question. You might be able to adjust the target setting in tsconfig.json to output code that is compatible with the older Javascript version. Try using ES5, or if that does not work you can try ES3.
dandar3 Google Play Services for eclipse always worked well. All project has a good synchronization.
But last time I caught bug of synchronization in android support appcompat project. Here is it:
All libraries in android support appcompat is correct. My system is Linux Mint 64. My default java is java-8-oracle(I tryed java-8-openjdk-amd64 no effect).
Mayby somebody faced that error? Please do not offer Android Studio. Thank you.
More details on the ticket on GitHub (link) but just to summarise it appears to be due to the fact that aidl tool only supports interfaces, it logs the message as an error and by design Google ADT plugin shows external errors as compiler errors.
The issue affects the Android Support Libraries 26.0.0 for Eclipse listed below, from which I will remove the offending .aidl files and release them again.

android-support-media-compat

My Android app is using 3rd party library that uses native libraries.
It is built with targetSdkVersion 21.
When running my app on Android 7 phones (in my example, LG G20), users start getting a visible error message upon process initialization.
The error message screenshot is attached.
When running the same app on Android 5.x and 6.x, there is no error shown to the user, although there is still a matching warning message in the log. Log message looks like:
library "/data/app/org.iotivity.base.examples.simpleclient-1/lib/arm/libocstack-jni.so" has invalid DT_NEEDED entry "./obj/local/armeabi/libocprovision.so"
ךibrary "/data/app/org.iotivity.base.examples.simpleclient-1/lib/arm/libocstack-jni.so" has invalid DT_NEEDED entry "./obj/local/armeabi/libocpmapi.so"
So it looks likes Android 7 "decides" to show to the end user a warning which is kept for the log only in previous versions.
I would appreciate:
1. Ideas on how the error message can be suppressed
2. Hints on what is the right solution for the issue (this is a 3rd party code, but I may try to tweak the build process)
Thanks in advance

So a few days ago I got my hands on an Arduino Mega ADK board, and the last couple of nights I have been setting up my development environment, getting to grips with the tools etc. The tools and libraries all work fine, for example I can get a program written in the Processing IDE to compile and run on an Asus Eee Pad Transformer TF101 running Android 4.03. But when I get it to try to compile and run one of the pre-written examples, it gives me a compiler error:
Android SDK Tools Revision 20

C:\NVPACK\android-sdk-windows\tools\ant\build.xml:693: Compile failed; see the compiler error output for details.
Total time: 7 seconds
And that's all the console seems to output as well, which is rather frustrating! As far as I'm aware all of my SDK versions, tools and plugins are all up to date. I've tried this using a Linux partition I have on my hard drive and it produces the same error message, although it mentions a problem with the package com.Android.future.UsbAccessory. Given what I've seen, it seems that the problem is with the tools, either my directory structure doesn't match up to what the correct setup is, or something else is wrong :S. If anyone has had similar problems, some help would be smashing! (For the record, my setup was done using the instructions on the Arduino website, although I already had the Android SDK tools installed).

It sounds like your haven't added in the support library to your project and/or you haven't downloaded it into your Android SDK.
The ADK1 demokit app targets API Level 10 (Android 2.3.3); That means you need to use the support libraries in your project and that's why the compiler is complaining about level 10 library dependencies not being available. The support libraries are a separate download in the SDK Manager, so you might not have them in your development environment.
In Android API Level 12 and higher, the USB Accessory protocol was added to the framework API, so there are two different ways to use the accessory protocol. So, you don't have to use the support libraries if you are targeting Honeycomb and higher versions, but you'll have to update the demokit app code to make this work.
Hope this helps.
So I've double checked my setup and started working on a project I had in mind, it seems to import the libraries appropriately. So far so good, but when I input:
ArduinoAdkUsb arduino;
void setup() {
arduino = new ArduinoAdkUsb(this);
//Other UI initialisation etc.
}
I get this error:

After the app has been built and installed onto the Android tablet I am using. Any thoughts how I can over come this? From what I can tell, this has no problem finding com.android.future.usb.manager to compile and install the program, but once it tries to run it can find it.
Based on this tutorial from http://stream.tellart.com/controlling-arduino-with-android/
In the examples RGB_Arduino the name, version and author variables are set at the top of the sketch.
Try adding in this section of code at the top of your arduino sketch just underneath the library imports
// accessory descriptor. It's how Arduino identifies itself to Android
char applicationName[] = "Mega_ADK"; // the app on your phone
char accessoryName[] = "Mega_ADK"; // your Arduino board
char companyName[] = "Freeware";
// make up anything you want for these
char versionNumber[] = "1.0";
char serialNumber[] = "1";
char url[] = "http://labs.arduino.cc/adk/"; // the URL of your app online
//initialize the accessory:
AndroidAccessory usb(companyName, applicationName,
accessoryName,versionNumber,url,serialNumber);
