I was trying out Urho3D on Android, and checking the forums, it seems that some people had success on running the Launcher app, however, I can’t get it to install. Is anyone having the same issue? I know the Android build had some changes recently, but it seems that people managed to get it working.
In some cases the application fails to install on my phone when the Google Play app has access to the internet. It’s a random issue not just with the Urho3D app.
Yeah I saw something about the google app store scanner messing up with the installation, so I disabled it. I tried installing it without internet, but it’s still failing. It fails to install too on android emulator (tried Android 8 and 9).
I almost always use SHARED lib type during development of the build script and I have never encountered any installation error before, at least not the one you guys described above.
Yes. That is the right page. That section was rewritten by me, unless I have I forgotten anything then what’s described in there is how I do the Android build.
I am using Linux host and IntelliJ IDEA as my IDE. I also just invoke Grade wrapper via CLI. At the initial stage I used Android Studio too. After the Gradle version upgrade recently, I believe you need to use preview version of the Android Studio. I wonder that is the cause. Using IntelliJ IDEA allows me to explore the bleeding edge of the Gradle with no sweat.
Tried again but this time building with ./gradlew build, same thing. As for the version, I’m using the Canary build of Android Studio, since it’s the only one that uses Gradle 3.5.
It’s not clear from your post what exactly is failing , any errors ? .
I don’t have any issues with either compiling or installing on any android device with any version ( I have many of them ) , never tried it on an emulator .
The following works for me ( I am using Mac , but I guess it should work also on a Linux machine)
Make sure that your .bashrc is configured correctly specifically these environment variables should be set pointing to your SDK and NDK.
ANDROID_NDK_HOME
ANDROID_NDK
ANDROID_HOME
In addition your PATH (in .bashrc) should also contain “Android/sdk/tools”
For development I am using
./gradlew assembleDebug -P URHO3D_LUA=0 -P ANDROID_ABI=armeabi-v7a -P URHO3D_ANGELSCRIPT=1
The generated APK can be found in
Urho3D/android/launcher-app/build/outputs/apk/debug/launcher-app-armeabi-v7a-debug.apk
installing using adb
adb install -r launcher-app-armeabi-v7a-debug.apk
Ok gonna try to do it that way, will update shortly.
And about that error, that’s the thing, it just fails to install with no error whatsoever. Here is a print from the emulator, and there’s no log too. The .apk I trying to install is the one generated on the release build named “launcher-app-release-unsigned.apk”.
Well the error is obvious , your apk is not signed .
launcher-app-release-unsigned.apk
You have to sign it with release keys.
using my way it will sign it with debug keys , will allow you to install it .
Once again I am not sure that using an emulator is the right way to go , you have to try it on a real device
Well, that may be, however, I enabled the installation from unknown sources, so that shouldn’t be an issue. However who knows, I will try it later. I also tried on a real device, same thing.
Update: following your way it works just fine! Apparently even if you turn on accept unknown sources on the android settings, you still gotta sign it. After following the tutorial here I self-signed the .apk and now it installs just fine.
Dammit, now what’s happening is that when I build the release version of the launcher app, I can’t run any examples, they all crash. There’s no log output either.
