I have an xamarin android project. It worked and built so far. Now I changed the jdk1.8 from the x86 to the x64 since the Xamarin Forms designer needs this version to work properly according to Xamarin. Now I get this error on build:
5>C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(1965,3): error MSB6006: "java.exe" exited with code 2.
I read that this might be related to newer support libraries of google. But i have the newest version and had it already before I made the change. I also tried reboot my pc, clean and rebuild and delete all bin and obj folders without success. And so far I haven't found more information what this error could be and how to solve it besides switch back to the x86 version of the jdk.
I found the issue, while getting the diagnostic build log. I added the xamarin forms nuget package for embedded forms. With that package, the references exceed the max of what android is able to handle. So I had to enable multi-dex first. Then it built again.

Every time I try and build my game, I am unable to find the APK file anywhere, I did however found the APK file in my recent folder, but it doesn't show up in the respective folders I initially selected or allows me to copy and paste the APK file into my Android device.
I don't even get any errors when the game is built (in fact, I get a message in my console stating that my build was successful) so I am confused to why my APK file is not showing up.
It happened after I recently updated my unity 5.6 to unity 2018.3.1 due to Oracle JDK is no longer free for commercial use and unity 2018.3 uses OpenJDK (I am using AdoptOpenJDK/JDK-12.0.1.12-hotspot). Once unity was installed, I didn't receive any errors only a few warnings within a few scripts (which was only a minor problem and I could solve easily).
However, when I go to player settings, I get this one warning: "failed to get available Android API levels. Make sure your Android SDK tools version is 25 or higher and you have an internet connection."
I made sure that my minimum API level is Android 8.0 'Oreo' (API level 26) and the target API level is Android 8.1 'Oreo' (API level 27), I also uninstall Android studio and reinstalled.
I even went as far as deleting all folders inside build tools and platforms from (appdata>local>android>sdk>buildtools) & (appdata>local>android>sdk>platforms) and updating the files for continuing the build.
However, all the methods I've tried have not to work, so I'm asking for help here. Please, does anyone know why is my APK file not appearing at all? Thank you in advance, I really appreciate it! :)
this solution helped me if Are you using the r22 of android SDK, if so, Google decided to move the aapt.exe from tools directory to build-tools//aapt.exe
A quick solution for this is co copy the aapt.exe file from build-tools and paste as shortcut on tools directory. Keep the shortcut name as aapt.exe
another solution is to download jdk(1.8 version is prefered)from oracle site ["http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html"]and set it instead of the build-in jdk form the project preferences then reboot
I've tried to Invalidate Caches/Restart and Clean Project several times.
I'm running the following version of Android studio.
Android Studio 3.2.1
Build #AI-181.5540.7.32.5056338, built on October 8, 2018
JRE: 1.8.0_152-release-1136-b06 x86_64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
macOS 10.13.6
The issue is the code is not being autocorrected by the IDE and none of the code assist features are working.
I left some intentional errors in my code and the compiler did not output any errors.
I'm also getting this error whenever I open a project:
Error while indexing /Users/christopherholmes/AndroidStudioProjects/QuizTwo/app/build/generated/not_namespaced_r_class_sources/debug/processDebugResources/r/com/example/christopherholmes/quiztwo/R.java
Not sure what to make of this.
EDIT
So I closed and re-opened Android Studio like 3 times and now things are back to normal. Crossing fingers... I will update if I run into any more issues.
EDIT
The problem has returned. To attempt to solve the problem I have
1) Upgraded Android Studio
2) Invalidated and Cleaned Cache
3) Rebuilt the project
I think you should check your directory of adb. It is important to fill correct directory for studio otherwise it will create problem.
The directory will look like../Users//Library/Android/sdk/platform-tools..This is default directory.Make sure your adb is located in that directory.
I installed Android Studio the other day to develop an app and even though it's not the first time I've used it, it's the first time I've installed it on this PC and I'm fairly new to all of it.
Problem: After installing Android Studio, I can't even make a "Hello_World" app, even the templates AS offers have a compiling error:
Where it doesn't recognize symbols like "Override". The Alt+Enter solution that offers is to Setup JDK which does nothing for all options or create annotation 'Override' which doesn't really seem like a good option.
These are both build.gradle files:
Things I've tried to fix it:
Reinstall Android Studio Multiple Times
Download JDK manually and change references.
Check Enviromental Values on system (Add JAVA_HOME and heck Path to be correct). Pretty sure both java and JDK work since in cmd I can run java and javac.
Obviously Build->Clean and File->Invalidate Cache + Restart
android.enableAapt2=false on gradle.properties
Trying to delete all java from my PC and reinstall bare minimum THEN install everything separatedly.
Install all SDK plataforms until Android KitKat.
It's worth noticing that in the past I had a lot of problems getting java to run in only one place (mainly because I install software in an HDD and have OS on another SDD).
Also, while installing AS for the first time I got into a BSOD because of VT-x having shitty interaction with virtualization of anti-virus (that took me a while to figure out) so it stopped halfway. However I've reinstalled a bunch of times so I don't know how that could matter.
The problem is very similar to this one
I'm practically lost here. I've been trying to fix this for three days and I've looked into dozens of Stack-Overflow posts with similar problems, haven't found a solution.
Any idea will be appreciated.
Thanks.
I repeated your error:
I made it by deleting Android SDK(not java SDK) in Android Studio:
File-Settings-AndroidSDK
Try to pick at least one and install
It seems that your problem is related to Android SDK
Okay guys, I've finally figured it out, thanks to artmmslv.
Android Studio's installer detected automatically - two versions of Android SDK which were corrupted (probably caused by BSOD messing up the installation).
I had to make sure to delete everything. Java SDK, Android SDK. Java JRE. Every data from Appdata or documents from Android Studio. Once the computer is clean from any traces of already installed plugins, modules, and whatnot, it should be able to set up perfectly fine paths.
Also, make sure to set up manually and correctly the Environmental Values of java (path edit and JAVA_HOME).
Thanks for the help.
I got a solution that was a problem for me.
(in Build.Gradle file) - It's the
Compile SDK version 32
//which was not the latest one,
I changed it from older (31) in old projects to (32)
And clicked: sync now,
it worked!!
Hope it helps:) Happy coding
I'm trying to get JavaFX applications to run on Android by using the Dalvik JavaFX-Android SDK (provided by the JavaFX Android porting team). So I downloaded the samples provided by the JavaFX Android porting team and have been trying to run one of them on Android without much success.
Using Eclipse with the Gradle plugin I imported the "HelloWorldFxml" sample project. Then I ran the Gradle task "./gradlew androidInstall" on the project like the README file told me. But unfortunately the task cannot execute because Gradle cannot locate my JDK:
(source: forumbilder.se)
Even though my JAVA_HOME system variable is correctly set and I havn't had a problem with it before:
(source: forumbilder.se)
Anyone that can provide some insight as to how I can fix this?
Versions: Eclipse Luna Service Release 1a (4.4.1), Gradle 2.2, dalvik-sdk-8u40-ea3, Android SDK Build-tools 21.1.2, Android SDK Tools 24.0.2
Edit: The console output when running "gradlew androidinstall" on a sample project:
Even though the error message doesn't specify it, maybe it's looking for javac in your PATH? In case it's not in there try adding ;%JAVA_HOME%\bin to the end of your PATH variable (and restart Eclipse afterwards, I've had the problem of running processes not getting changes to environment variables before).
Check the Java setting in Eclipse:
Window -> Preferences
Java -> Installed JREs
Make sure that your JDK 1.8 is listed there. If it's not, add it using the Add... button.
Once the JDK is known to Eclipse, make sure that your project's settings use that JDK as a compiler, and the Gradle plugin should be able to pick up the setting from there.
In a pinch, you should also be able to run Gradle from the command line, and it should work fine since you already set the %JAVA_HOME% variable.
Basic Note
Since the release of dalvik-sdk-8u40-ea3, and in very short time, the JavaFXPorts team has released a few new versions, all of them simplifying all the process of porting a JavaFX application to Android or iOS.
They released dalvik-sdk-8u40-ea4 and they announced the release of a new plugin, that will simplify to the minimum the steps to create a mobile application from JavaFX.
While this answer may not help the OP in his particular problem, definitely it will help him and others, since everything is really simplified.
New approach
With this plugin, there's a new way of creating the HelloWorldFxml application for Android.
The new javafxmobile-plugin allows you to generate the apk with a single 'build.gradle' file.
You can find this an other basic samples here, and download the repository here.
You won't need to edit a single line, just type this on the command line, on the root of the sample, with your device connected:
gradlew androidInstall
As for previous releases, you will need JDK8u40 and Android SDK installed. No need for dalvik-sdk though, it's retrieved by the plugin.
Notice that you can open these samples from your IDE, so you will be able to modify them, and run them locally or build again the apk for your device.
Had this problem, too.
My proberties:
-Windows 7
-Dalvik SDK (dalvik-sdk-8u60-b5)
-JDK 8 (newest Version 8_60 / IMPORTANT: JDK not JRE)
-And I tried also the HelloAndroid project provided by the Dalvik-SDK-download.
So i execute the command line: gradlew installDebug
My probelm was nearly the same.
"Fail to find JDK. Please make sure there is a JAVA_HOME or JAVA8_HOME systemvariable."
#1
Created these proberties. Just like described in this post:
How to set java_home on Windows 7?
So to make everything sure, I created both with the same path. Cause I don't know exactly which one is used by gradle.
#2
This is really the hack that helps me out. Found this also in StackOverflow.
Write in your build.gradle under the android{..} stuff this line:
retrolambda {
jdk 'C:/Program Files/Java/jdk1.8.0_60' //<--your JDK-path
}
it looks like that
Then execute the same command line again and it worked for me.
I think only the 2. steps was the solution, cause I guess gradle don't look for the variable if there is a direct path to the jdk.
I've tried building the CSEmptyTemplate project in eclipse for android but have run into a host of issues with it.
Looking at the documentation, it doesn't appear as if it should be this difficult.
Firstly, I've installed cygwin and installed the devel package to get make.exe and gcc compilers. I'm also using cygwin as part of the tool chain.
However, the error I keep getting is 'make: *** No rule to make target `all'. Stop.'.
Any advice on fixing these issues would be appreciated.
edit: Found the make files. I was just an idiot last night when working on this.
There shouldn't be any additional steps required to build Chilli Source for android on windows, just the simple steps listed on the website here: http://chilli-source.chilli-works.com/docs/?page_id=67
However setting up the Android Development Tools with the NDK can be a bit of a pain. Judging by the error your getting my gut feeling is that something isn't set up correctly there.
Chilli Source requires the latest versions of the SDK, NDK and ADT. Can you ensure you have:
Android API level 21.
The latest versions of the Built Tools, Platform Build Tools and Google Play Services.
NDK revision 10c.
The latest ADT is also missing a couple of things that means it can't be used out of the box.
It doesn't come with the native dev tools which can be acquired by doing the following:
Go to "Help" then "Install New Software..."
Select "Android Developer Tools Update Site - https://dl.google.com/android/eclipse". You make have to edit it to instead point to https://dl-ssl.google.com/android/eclipse
In Developer Tools select and install Android Native Development Tools.
It also doesn't come with ant. This isn't causing your issue, but it will cause issues later on, so get it following these steps:
Go to "Help" then "Install New Software..."
Select "Juno - http://download.eclipse.org/releases/juno"
In General Purpose Tools select and install Eclipse Plug-in Development Environment.
Now that you've got everything required, ensure that you've got it set up correctly:
The correct version of the SDK selected the Android tab in preferences.
The correct version of the NDK selected in the Android/NDK tab in preferences.
Android 5.0 selected in the Android tab in Project Properties.
Finally, on windows you also need Cygwin. It's been a while since I've used it (I'm not a fan of cygwin so I do my Android development in a Ubuntu virtual machine) but only the "devel" package is needed iirc, so make sure you've at least got that.
Hopefully ensuring all of that is set up correctly will fix your problem!
