| Allegro 5 Android build |

I'm experimenting with Android and, after installing Android Studio, the Android SDK and NDK, the first thing I did was to build Allegro 5 following the instructions in the README_android.txt file. I setup a x86 toolchain to be able to test Allegro in the Android emulator and, after a few hurdles along the way, I managed to build Allegro successfully. However, I'm having trouble running the Allegro examples on the Android emulator. First of all, the README_android.txt seems to be a bit outdated since there's no bin directory containing the final .apk; instead, the .apk files are generated in app/build/outputs/apk/debug, e.g.: I installed the .apk but even then attempting to run the app as instructed in README_android.txt returned an error: generic_x86:/ $ am start -n org.liballeg.examples.ex_draw_bitmap/.Activity
Starting: Intent { cmp=org.liballeg.examples.ex_draw_bitmap/.Activity }
Error type 3
Error: Activity class {org.liballeg.examples.ex_draw_bitmap/org.liballeg.examples.ex_draw_bitmap.Activity} does not exist.Seems like the README_android.txt file is outdated here again since apparently there's no such package installed: generic_x86:/ $ pm list packages ... package:org.liballeg.ex_draw_bitmap But using org.liballeg.ex_draw_bitmap instead doesn't solve the issue: generic_x86:/ $ am start -n org.liballeg.ex_draw_bitmap/.Activity
Starting: Intent { cmp=org.liballeg.ex_draw_bitmap/.Activity }
Error type 3
Error: Activity class {org.liballeg.ex_draw_bitmap/org.liballeg.ex_draw_bitmap.Activity} does not exist.Using MainActivity as indicated in the manifest gives the same result. The application icon appears in the Android emulator but the application closes/crashes immediately after clicking on it. So at this point I'm lost. Any help welcome. Thanks. [EDIT:] Nevermind, using the binaries from the maven repository as described in the wiki worked. [EDIT 2:] Sorry for bumping this but now the Allegro sample program using the binaries from the maven repository works fine on the Android emulator but crashes on a real tablet (an old cheap chinese tablet with Android 4.0.3).

Does it work in a 4.0.3 emulator? I'll try myself when I get a chance - as far as I remember I compiled with SDK 15 which happens to be exactly 4.0.3 as oldest supported version. I have not seen the missing stderr in reloc_library error myself - but usually things like that point to an API incompatibility. -- |

Elias said: usually things like that point to an API incompatibility Yeah, I found some information suggesting that but the tablet reports SDK 15: root@android:/ # cat /system/build.prop # begin build properties # autogenerated by buildinfo.sh ro.build.id=IML74K ro.build.display.id=20120302.180049 ro.build.version.incremental=20120228 ro.build.version.sdk=15 ro.build.version.codename=REL ro.build.version.release=4.0.3 ro.build.date=Tue Feb 28 18:00:56 CST 2012 ... I will download a 4.0.3 emulator and report back. [EDIT:] It took me a long time to get a 4.0.3 image running in the emulator. I was getting this: {"name":"611676","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/9\/b\/9bc9c1694e00d4bd40ec71f6e27f31f6.png","w":378,"h":584,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/9\/b\/9bc9c1694e00d4bd40ec71f6e27f31f6"} It seems to be a common issue with the 4.0.3 image from Android Studio with an apparently random solution. When I finally got it to work I tried running the Allegro example and got this: I/ActivityManager( 1191): START {act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10200000 cmp=com.example.myfirstapplication/.MainActivity} from pid 1307

Not knowing if the error was caused by the emulator issue in the first screenshot, I tried running the "Hello World" example from Android Studio and it worked as expected: {"name":"611677","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/4\/3\/431a30abfd4466ef852ab1bf7af794ea.png","w":378,"h":584,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/4\/3\/431a30abfd4466ef852ab1bf7af794ea"} So the problem remains with the Allegro program not running on Android 4.0.3 whether it is in the real tablet or in the emulator. [EDIT 2:] Seeing that the error was on the nativeOnCreate() function, I rebuild the project with the debug version of Allegro and got this: ...

I've tried all kind of options -using the prebuilt binaries, building manually- always with the same result: the Allegro programs work -kinda- in the API 28 emulator but not in the real tablet nor in the API 15 emulator. Am I doing something wrong or is Android 4.0.3 no longer supported?. As a side note, I've tried running the NDK samples and some of them work correctly on the Android 4.0.3 tablet while others report similar errors when loading native libraries (others simply require a higher API so they won't run on the 4.0.3 tablet).

My current phone doesn't connect properly to my laptop. The drivers are faulty and no one ever bothers to update them on their end. On a brighter note, I'm getting a new phone, and I want another Android. I liked my Motorola Droid Turbo 2 but as I said it doesn't work with my laptop. If I get a new phone here today maybe I can help test this. Recommendations for a new phone?

D/AllegroActivity( 1921): nativeOnCreate failed Can you make sure you are using a debug build? It seems your logcat only shows the unconditional Log.d lines, but none of the ALLEGRO_DEBUG. E.g. here is nativeOnCreate: https://github.com/liballeg/allegro5/blob/ec6c8f2dbba8ba93f215295b0ee60fe1750eb15b/src/android/android_system.c#L173 And you don't even get the initial "entered nativeOnCreate" log message. Knowing which of the errors inside of nativeOnCreate get triggered would help a lot. -- |

The last log in my previous post was made with the debug build of Allegro, you can see the other debug messages except the one you mention. Maybe I accidentally omitted it when pasting the log. Anyway, here's a fresh, unfiltered log: D/dalvikvm( 8863): Late-enabling CheckJNI

Hm, can you check your .apk (it's just a .zip) and see if it has libnative-lib.so inside? -- |

Yes, the file is in there. In fact, as I said before, the exact same .apk, built using the x86 toolchain, works in the API 28 emulator but not in the API 15 emulator. Of course, for the real tablet I'm using the arm toolchain and there the app also fails when trying to load libnative-lib.so.

Which is probably due to that initial error you saw where "stderr" could not be found which the .so depends on - and I guess sometimes it just says "not found" instead of "dependencies missing". Anyway, not sure what to do - I don't have an actual 4.0.3 device anymore myself. -- |

That error was present when using the prebuilt binaries from the maven repository which, I think, were built for a higher API; that's consistent with the information you can find about the error and also there's the fact that the python script uses -DANDROID_TARGET=android-26 when building Allegro. So the prebuilt binaries are likely the cause of the stderr error when trying to use them on Android 4.0.3. It was only until I built Allegro manually with -DANDROID_TARGET=android-15 that the libnative-lib.so error appeared. So, I guess the short answer is Allegro won't work on Android 4.0.3? Aim for a higher API?. That sucks when all you have to test is and Android 4.0.3 tablet.

The target SDK should always be the highest one available at the time - it does not mean older SDKs will not work. What is important in the min SDK: https://developer.android.com/guide/topics/manifest/uses-sdk-element In fact, you cannot put any apps on the play store where target SDK is less than 26, so using a value less than 26 does not make too much sense. You can still set the min SDK to 15 and it will work fine on 4.0.3 devices. -- |

Yeah, I meant aim for a higher minimum SDK. Anyway, it was obvious the error was caused by the dlopen() call in android_system.c. I've read that there's been some changes in the way dlopen() works in Android, so I changed line 249 in android_system.c: system_data.user_lib = dlopen(user_lib_name, RTLD_LAZY|RTLD_GLOBAL); and hardcoded the full library path in the Android device like to this: system_data.user_lib = dlopen("/data/data/org.liballeg.speed/lib/libnative-lib.so", RTLD_LAZY|RTLD_GLOBAL); After doing this, the libnative-lib.so error was gone and it was instead replaced by an allegro_main-debug not found error. Adding the corresponding loadLibrary("allegro_main"); line in MainActivity.java solved the issue and now the Allegro demo is running both in the API 15 emulator and in the tablet. This is a cheap workaround as it requires to hardcode the path for dlopen() but I guess it's a good start.

Interesting. I'm not sure if the /data/data folder exists on newer devices, so might want to only do that if the device is on SDK 15. -- |

Maybe do the original call to dlopen(), if it fails attempt the call with the full path and only if both fail return an error?.
