As far as signing the app is concerned I followed the instructions here. Just scroll down to the "Sign your app from command line" section.

You must first create a key: Follow step 1, here. I believe the keytool is found inside your sdk/tools folder, if I remember correctly.  

Assuming you have generated a key, you then export some variables like so:

export P4A_RELEASE_KEYSTORE=~/keystores/<your-new-key>.keystore

export P4A_RELEASE_KEYSTORE_PASSWD=<your-new-key>

export P4A_RELEASE_KEYALIAS_PASSWD=<your-new-key>

export P4A_RELEASE_KEYALIAS=<your-key-alias>

Then: buildozer -v android release to build the app.

I built my app using SDK 23 and build-tools 28.0.3. I placed the .keystore file in the .buildozer/.../bin directory and following step 2 from first link above, I run:

~/.buildozer/android/platform/android-sdk-23/build-tools/28.0.3/zipalign -v 4 myapp-release.apk myapp-release-optimized.apk

and

finally according to step 3 I run:

~/.buildozer/android/platform/android-sdk-23/build-tools/28.0.3/apksigner sign --ks myappname.keystore --out MyApp.apk myapp-release-optimized.apk

where I had to enter the key.

The above worked for me.

Hopefully, the instructions will get you and/or someone else sorted out.

Regards,

Thomas

Thanks I have resolved but I have new problem, when I developed the apk in Google the api must be 26
The current API target level of my is 19,how update at 26 ? thanks sorry my English regards

[Thomas S.]

You should first build the app targeting api 19. Then, delete the dists folder found in the directory .buildozer\android\platform\build. Set api 26 by opening buildozer.spec and make the following change:

# (int) Android API to use

android.api = 26 

Rebuild.
