Does anyone know if jxcore-cordova works with Lenovo Tab 2 A10-70F? #112

Closed AlexZhouAA closed 8 years ago

AlexZhouAA commented 8 years ago

I tried this device and found jxcore.isReady function never got called.

However, all the same code works pretty well with Samsung Tab S & Asus ME173X.

The following is some details about the device: http://www.walmart.com/ip/Lenovo-ZA000001US-10-16gb-2-Gb-Android-4.4/44728585

Thanks in advance for any help

Since this is Android 4.4 you may try to debug the webview in chrome's inspector. Maybe you'll find something? A note on how I was able to do so is here: https://github.com/jxcore/jxcore-cordova/issues/7#issuecomment-121370015

Thank you for your response, I already updated it to Android 5.0.1 Here are some debugging info,

Is com.mediatek.common.telephony a plugin that you use?

E/MPlugin ( 4341): Unsupported class: com.mediatek.common.telephony.IOnlyOwnerSimSupport

I wonder if the problem is related with long app startup. Are you able to run any of the bundled samples to see if they run on the device? You may use jxc command for this.

AlexZhouAA commented 8 years ago

I tested the apk on Samsung & Asus devices, they're all doing well. com.mediatek.common.telephony does not come from a plugin. Since this device use MTK 8165 as its cpu made by mediatek, I think this class from the device itself. By the way this device runs 64-bit Android 5.0.1 system, I'd like to know whether cordova-jxcore supports 64-bit Android system or not?

Thanks for your patience.

AlexZhouAA commented 8 years ago

Where can I get a 64-bit version of libjxcore.so？ I think that would solve the problem.

obastemur commented 8 years ago

@AlexZhouAA 64bit ARM or Intel ?

AlexZhouAA commented 8 years ago

64 bit ARM

Sorry, I just saw it's ARM 64. JXcore would compile for 64bit ARM though but the regular fat binary doesn't have the bits for that. We also have some devices here with 64-bit SoC . None of them has the Android with 64 bit installed.

Adding 8Mb more on fat binary for 64Bit Android OS (maybe 0.00001% of the actual devices at max has that software installed) This is a bit tricky decision. However we should provide a way for you, so you can have this option anyway.

That would be great! You're really a life saver.

I'm pretty sure the 64 bit android system will be more and more popular.

See the instructions https://github.com/jxcore/jxcore/blob/master/doc/Android_Compile.md

Thank you, I'll try it

@obastemur : I followed your instruction to compile for 64 bit Android, but no luck. https://github.com/jxcore/jxcore/blob/master/doc/Android_Compile.md

If without "--embed-leveldown" presents, run "build_scripts/android_compile.sh ~/androidNDK/", I did "Compile as a Static Library" successfully. However, when I tried to run "~/android-ndk-path/ndk-build", I got error like


Android NDK: ERROR:/home/zhou/jxcore-cordova/src/android/jni/Android.mk:level: LOCAL_SRC_FILES points to a missing file    
Android NDK: Check that /home/zhou/jxcore-cordova/src/android/jni/../jxcore-binaries/libleveldb_arm.a exists  or that its path is correct   
/home/zhou/Downloads/androidNDK/build/core/prebuilt-library.mk:45: *** Android NDK: Aborting    .  Stop.

I realized I have to compile with "--embed-leveldown", and then got the following,

I noticed the folder leveldown-mobile is empty. Finally I found this link, https://github.com/jxcore/jxcore/issues/658 I copied all things from leveldown-mobile/tree/791effbccf114ec5b449aa467fe451098ed7da86 to jxcore/deps/leveldown-mobile/ and ran "build_scripts/android_compile.sh ~/androidNDK/ --embed-leveldown" again. This time I got,

Now I have no idea what to do. What I did wrong?

Thanks

@AlexZhouAA are you using LevelDB with your app ?

AlexZhouAA commented 8 years ago

No, I don't. I tried to run ~/android-ndk-path/ndk-build to update JXCORE binaries, I got error


ova/src/android/jni/Android.mk:level: LOCAL_SRC_FILES points to a missing file    
Android NDK: Check that /home/zhou/jxcore-cordova/src/android/jni/../jxcore-binaries/libleveldb_arm.a exists  or that its path is correct   
/home/zhou/Downloads/androidNDK/build/core/prebuilt-library.mk:45: *** Android NDK: Aborting    .  Stop.

This error should have nothing to do with my app.

obastemur commented 8 years ago

See https://github.com/jxcore/jxcore-cordova/tree/master/src/android There are two build scripts. One with leveldown and another without. Gonna take care of the leveldown android ARM64 issue anyways. Thanks for reporting it.

AlexZhouAA commented 8 years ago

Thanks, I'll try the one without leveldown.

ktrzeciaknubisa commented 8 years ago

Me too I have 

make[1]: *** [/Users/nubisa_krzs/Documents/GitHub/jxcore/out/Release/obj.target/leveldb/deps/leveldown-mobile/deps/leveldb/leveldb-1.17.0/db/db_impl.o] Error 1
make: *** [jx] Error 2
compilation aborted for arm64 target

when running 

sudo ./build_scripts/android_compile.sh ~/android-ndk-r10d --embed-leveldown

with arm64 enabled:

# android_compile.sh
ARM64=out_arm64_droid
AlexZhouAA commented 8 years ago

@obastemur One more question, When I run ~/android-ndk-path/ndk-build, how can I choose build_default.sh instead of build_leveldown.sh?

Thanks

ktrzeciaknubisa commented 8 years ago

@AlexZhouAA Just run one either build_default.sh or build_leveldown.sh. It calls ndk-build. However I needed to use something like this to make it work:

export PATH=$PATH:/Users/nubisa_krzs/android-ndk-r10d/
./build_leveldown.sh /Users/nubisa_krzs/Documents/GitHub/jxcore/out_android/android/bin

But you need to have android binaries compiled first. The above path [...]/out_android/android/bin is my result of:

sudo ./build_scripts/android_compile.sh ~/android-ndk-r10d --embed-leveldown
AlexZhouAA commented 8 years ago

@ktrzeciaknubisa Thanks, I'll try that.

AlexZhouAA commented 8 years ago

Now I ran ~/android-ndk-path/ndk-build successfully, but there're nothing related to arm64 generated under folder jxcore-cordova/src/android/libs .

I checked folder under jxcore-cordova/src/android/jxcore-binaries, there're lots of file named as *_arm64.a

I also examined the file jxcore-cordova/src/android/jni/android.mk, there're no statements related to arm64. Is this the reason that caused no arm64 *.so generated?

AlexZhouAA commented 8 years ago

I ran $> build_scripts/android-configure.sh ~/androidNDK/ created android-toolchain and android-toolchain-intel.

Modified build_scripts/android_compile.sh as following, ARM64=out_arm64_droid After ran $> build_scripts/android_compile.sh ~/androidNDK/ I successfully build jxcore as arm64 static library.

And then I followed below to update jxcore binaries of jxcore-cordova, https://github.com/jxcore/jxcore-cordova#updating-jxcore-binaries-optional Everything went smoothly, no errors reported.

I got three folders generated under folder jxcore-cordova/src/android/libs


libs
    +armeabi
    +armeabi-v7a
    +x86

No folder like arm64-v8a or x86_64 appears.

What I did wrong? How can I apply arm64 static library to jxcore-cordova?

I appreciate all the help from obastemur and ktrzeciaknubisa I can tell it's pretty close to success, please help

AlexZhouAA commented 8 years ago

After I applied the newly compiled .so files to jxcore-cordova, and re-added the plugin, My app is up and running on the 64 bit android device.

Thanks for all the help, very appreciated

obastemur commented 8 years ago

@AlexZhouAA It could be really nice if you can contribute a basic how to tutorial on this.

AlexZhouAA commented 8 years ago

I really did nothing more than the instructions you guys provide. If you think it may benefit others, I'd be very glad to share what I did.

  1. Download jxcore and create android toolchain

    ~$ git clone https://github.com/jxcore/jxcore
~$ cd jxcore
~$ build_scripts/android-configure.sh ~/Downloads/androidNDK/
  2. Refer to this link to compile jxcore as a arm64 enabled static library. I chose the one without the switch --embed-leveldown

  3. Download jxcore-cordova and update JXcore binaries, run the following,

    ~$ git clone https://github.com/jxcore/jxcore-cordova.git
~$ mkdir ~/jxcore-cordova/src/android/jxcore-binaries
~$ cp -f /jxcore/out_android/android/bin/* jxcore-cordova/src/android/jxcore-binaries/

  4. Recompile .so files

    ~$ cd jxcore-cordova/src/android/jni
~$ ~/Downloads/androidNDK/ndk-build

    If ndk-build complaints the below things,

    Android NDK: ERROR:/home/zhou/jxcore-cordova/src/android/jni/Android.mk:level: LOCAL_SRC_FILES points to a missing file    
Android NDK: Check that /home/zhou/jxcore-cordova/src/android/jni/../jxcore-binaries/libleveldb_arm.a exists  or that its path is correct   
/home/zhou/Downloads/androidNDK/build/core/prebuilt-library.mk:45: *** Android NDK: Aborting

    I think ndk-build calls jxcore-cordova/src/android/build_leveldown.sh by default. I don't know how to change that. As a workaround, here is what I did, 

    Rename file  jxcore-cordova/src/android/build_leveldown.sh to something else
Rename file Rename jxcore-cordova/src/android/build_default.sh to jxcore-cordova/src/android/build_leveldown.sh

    And then run again,

    ~$ ~/Downloads/androidNDK/ndk-build
  5. Re-add the plugin, copy the updated jxcore-cordova to the root path of your app 
    ~$ cd root-path-of-your-app
~$ cordova plugin rm io.jxcore.node
~$ cordova plugin add jxcore-cordova/

    6.
