Sync failed in Android Studio #76

Closed Massimaux closed 5 years ago

Massimaux commented 5 years ago

Hi,

I downloaded the source code from https://github.com/ComThings/PandwaRF/tree/master/SW/Android/SampleApps/PandwarfSDK and opened it in Android Studio. Unfortunately, the sync procedure failed and I was not able to build apk from your sample codes.

What could be the problem?

trollwookiee commented 5 years ago

I just tested against gollum:0.9.9 and gollum:0.9.12 and both sync and compile worked.

Can you describe more precisely what kind of sync issue you face ?

Massimaux commented 5 years ago

Hi,

There is no sync issue anymore. This is the status with respect to its installation and working on different smartphones:

do you have a log for HUAWEI P10 Lite crash ?

Massimaux commented 5 years ago

How can I get the log?

trollwookiee commented 5 years ago

adb logcat

Massimaux commented 5 years ago

I will try to obtain it later today.

BTW, the playstore PandwaRF app works perfectly on this HUAWEI P10 Lite.

Try to build your app with "armeabi-v7a" In your build.gradle:

defaultConfig {
...
   ndk {
            abiFilters "armeabi-v7a"
        }
...
}

Thank you! Crash solved.

If I have a data buffer of 15-20 Kbytes to be transmitted, how can I minimize the probability of Tx failure:
