I have a working piece of code which works when built on other machines but if i build using my machine, the adapter does not show up. No elements of the adapter are populated.
I have RecyclerView inside a ViewPager.
I have updated SDK and Android Studio as well.

Please help
I think your build.gradle is missing design dependency,
try compiling this dependency

I get following exception log if I try to open my app on API 16 (on API 27 it is working):

All warnings are correct because the methods like "NotificationChannel" are not existing in API 16.
And the code I use for example the "NotificationChannel" is not executed because I check for the Build.VERSION.SDK.INT!
What exactly is the problem? Can anybody help?
I used the "FileUriException" in a catch statement and this caused the the problem.
Instead of:
catch(FileUriException e) {
}
I do now:
catch(Exception e) {
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.N && e instanceof FileUriExposedException) {
}
}
I have some app that needs to be installed on the system directory. I've seen several ways which use adb commands to do so. I think this must be done using the adb shell on the pc and a usb cable. But is there any way for the app to copy itself from Data to system directory without needing a pc?
As I know we can run commands within android app using Runtime. So, I tried this code within onCreate, but it doesn't copy the .apk file. This is the code:
boolean isSystemApp = (getApplicationInfo().flags
& (ApplicationInfo.FLAG_SYSTEM | ApplicationInfo.FLAG_UPDATED_SYSTEM_APP)) != 0;
if (!isSystemApp) {
Toast.makeText(getApplicationContext (), "not system app", Toast.LENGTH_LONG).show();
try {
String [] commandsOldVersions = {"adb shell\n", "su\n", "mount -o rw,remount /system\n",
"adb push eyedetection.apk /sdcard/\n", "adb shell\n","su cd /sdcard\n"
, "mv eyedetection.apk /system/app\n","su chmod 644/system/app/eyedetection.apk\n" };
String [] commandsNewVersions = {"adb shell\n", "su\n", "mount -o rw,remount /system\n",
"adb push eyedetection.apk /sdcard/\n", "adb shell\n","su cd /sdcard\n"
, "mv eyedetection.apk /system/priv-app\n", "su chmod 644/system/priv-app/eyedetection.apk\n" };
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) {
// for 4.3 and higher versions, execute the following line (because they've changed their system files hierarchies):
Process process = Runtime.getRuntime().exec(commandsNewVersions);
BufferedReader br= new BufferedReader(new InputStreamReader(process.getInputStream()));
Log.i("cmd", br.readLine());
}//end if
else {
//for older version, execute this line instead
Process process= Runtime.getRuntime().exec(commandsOldVersions);
BufferedReader br= new BufferedReader(new InputStreamReader(process.getInputStream()));
Log.i("cmd", br.readLine());
}//end else.
Runtime.getRuntime().exec("adb reboot");
}//end try.
catch (IOException e) {
Log.i("eyedetection", "error in executing adb commands");
}//end catch.
}//end if the app is not system app.
else {
Toast.makeText(getApplicationContext (), "It's system app", Toast.LENGTH_LONG).show();
}
The app doesn't crash, but I get these lines in the logcat:

I couldn't figure out the problem from the logcat. Why the code doesn't work? Is it possible to let the app copy itself to another folder on a rooted device, or must we use usb cable?
The 'adb xxx' command can only be used in a PC shell, not in Android/Linux shell.
That is, you should use
Runtime.getRuntime().exec("reboot")
instead of
Runtime.getRuntime().exec("adb reboot").
Hi Friends at Stack Overflow
I recently run into a problem when implementing Fiksu SDK in my Android app. A brief intro, Fiksu SDK is a marketing tool to register installation and events. All the methods related to Fiksu is in a .jar file called "ASOTracking.jar"
The problem:
The library is setup correctly, there is no error reported by Gradle when project compiles and I can even make debug apk. However, it throws "java.lang.NoClassDefFoundError" at runtime when it tries to initialize the SDK.
The log:

My local environment:
Project is developed on Android Studio
I'm using Mac OS X 10.8.5 Mountain Lion
compileSdkVersion 21, buildToolsVersion "21.1.2",
gradleVersion = '2.2.1', com.android.tools.build:gradle:1.0.0
This is a multi-module project. Application module calls "userInterface" library module and this SDK lies in this library module.
What I've tried:
I do make sure the SDK (jar) file is properly setup and there is no compile error reported by Gradle
I make sure there is no syntax error at the places where SDK methods is called
I checked the dependency of the module that calls this SDK to make sure there is no dependency problem. I go so far that I even trim the whole dependency tree (I know it's unnecessary).
I tried deleting the "build" directory of all modules and rebuild the whole project
I performed the "Invalidate Cache/Restart" operation in Android Studio
I performed "./gradlew clean" command via Terminal at both root directory and application module directory.
I consulted the following links in STO with no success:
Android Studio - Importing external Library/Jar
Android Studio: Add jar as library?
Android studio Gradle Could not find method compile()
Getting "Caused by: java.lang.VerifyError:"
Unable to find classes in Android library file
NoClassDefFoundError with libraries in Android Studio
Final thoughts:
I need some serious help because I've tried everything I know. This SDK worked fine before I migrated this project from Eclipse. Now it throws weird exception when running in Android Studio.
There is one last thing that's kinda suspicious --- the classpath file in Android Studio (the ***.imi file), I re-arrange the classpath entries in it and it still doesn't work.
Thank you guys advance for your help!
New Findings
My GS4 (Android 4.3) cannot run this app, but HTC One M8 (Android 5.0.1) can run it
Root Cause
65K methods limit
Refer to this document: https://developer.android.com/tools/building/multidex.html
Basically there is a methods reference limit and the only solution is to use multidex configuration. However there are implementation for platforms prior 5.0 and after 5.0
Solution
The solution is described in both:
https://developer.android.com/tools/building/multidex.html
https://developer.android.com/reference/android/support/multidex/MultiDexApplication.html
For my project, since it supports older version of Android, I go with the "multidex support library" solution.
Set the build tool version of all library modules and app module to the latest 21.1.2
For module that has Application class, add compile 'com.android.support:multidex:1.0.0' as dependency
Refer to this link to modify your application class. https://developer.android.com/reference/android/support/multidex/MultiDexApplication.html
At the same gradle script, under android -> defaultConfig block, add "multiDexEnabled true"
If your system gives "Java Heap Size" error, in the app module's gradle script, add the following
dexOptions {
incremental true
javaMaxHeapSize "4g"
}
I have one user running my app getting the following error, which I can't reproduce on my phone or I haven't see on any other phone.
Can any one suggest why this isn't working just for this user, they say that the Googlemaps app works fine.
Note I have Google API and maps in my manifest too.

We've recently decided to disable code obfuscation in our Android build, since while it makes the final APK slightly larger, it makes debugging so much more difficult.
Ever since we've done that, I keep running into crashes in our app that were not present before, i.e. while obfuscation was still active. Usually these crashes are caused by Java VerifyErrors or NoSuchMethodErrors.
Here are two of these errors I suddenly see when I disable obfuscation:
Could not find method org.apache.http.HttpConnectionMetrics.getResponseCount, referenced from method com.google.android.apps.analytics.PipelinedRequester.sendRequests

I could resolve this error by disabling class merging via !class/merging/*
Another error I was seeing was this:

This one I could resolve by setting !method/propagation/*
But why do these problems only appear with obfuscation disabled? Shouldn't one have no impact on the other?
The obfuscation was saving you because it was renaming your copies of the Apache HttpClient classes to names that wouldn't collide with the copies of those classes already present in Android.
Nasty place to be... you might want to consider not using Apache HttpClient at all, and using the in-built HttpURLConnection class as suggested by Jesse Wilson:
http://android-developers.blogspot.com/2011/09/androids-http-clients.html
You could try this Android-friendly veneer on HttpURLConnection:
https://github.com/kevinsawicki/http-request
If you really have to use Apache HttpClient, either use the old version embedded in Android, or try tweaking your ProGuard configuration to just obfuscate the HttpClient libraries.
