Implement FIleProvider in hard coded template

[ThomasCWright]

Used https://stackoverflow.com/q/38983649/7312441 as starting point, however, following error thrown

11-23 12:09:14.323 23238 5039 I python : jnius.jnius.JavaException: JVM exception occurred: file:///./blank_9x9.png exposed beyond app through ClipData.Item.getUri()

Quick search reveals promising post kivy/plyer#500 (comment)

also:
https://github.com/alecvn/kivy-android-camera#kivy-example-for-android-camera

but will create a new issue for this if next try can't make tests. Passed tests but still too big a rabbithole for task in hand. Off to backlog

Due to the differing nature of print services on Android, the MVP needs to be able to fully share an image file via the app's FIleProvider.

On success, issue #12 should be looked at for completion.

Update C:\Users\tcw25\Documents\GitHub\Sudoku\.buildozer\android\platform\build-arm64-v8a\build\bootstrap_builds\sdl2\templates\AndroidManifest.tmpl.xml

Looks like a great solution for future use of androidx but because

This requires android.api=28 or greater

No good for developing for Dad who's on api=25

[ThomasCWright]

OK. Back to the following link

[ThomasCWright]

Adding to main.py:

FileProvider = autoclass('android.support.v4.content.FileProvider')
Context = autoclass("android.content.Context")
Environment = autoclass("android.os.Environment")

[ThomasCWright]

support-v4-24.1.1.aar is required:
Downloaded here: https://maven.google.com/web/index.html?#com.android.support:support-v4:24.1.1
Added to buildozer.spec:

# (list) Android AAR archives to add (currently works only with sdl2_gradle
# bootstrap)
android.add_aars = support-v4-24.1.1.aar

[ThomasCWright]

Now modify existing share function to take advantage of FileProvider class:

photoUri = FileProvider.getUriForFile(
Context.getApplicationContext(),
"org.test.myapp.fileprovider",
photoFile
)

Trying forked p4a:develop with changes according to:
https://github.com/alecvn/kivy-android-camera#kivy-example-for-android-camera
$ pip install -e .
$ buildozer android debug => gives correct target API==29 but no change in AndroidManifest.xml
=> buildozer appclean and repeat step above

[ThomasCWright]

Deleting fork of p4a and cloning https://github.com/pavelsof/python-for-android.git instead

From kivy/python-for-android#2200 (comment)

Insert

   <provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="{{ args.package }}.fileprovider"
        android:grantUriPermissions="true"
        android:exported="false">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths" />
    </provider>

into AndroidManifest.tml.xml

Reverting to https://github.com/Fak3/python-for-android.git and following comment

conda install -c anaconda python=3.7

[ThomasCWright]

Giving up on Fak3 PR and reverting to stock buildozer to try my luck with some hard wiring

[ThomasCWright]

Following this comment

• buildozer android debug
• Add path to FileProvider lib:
  android.add_aars = ./support-v4-24.1.1.aar
• .buildozer/android/platform/build-arm64-v8a/dists/BVWSudoku__arm64-v8a/templates/AndroidManifest.tmpl.xml updated
• Then create a folder named xml in the .buildozer/android/platform/build-arm64-v8a/dists/BVWSudoku__arm64-v8a/build\src\main\res directory and create a file named file_paths.xml
• buildozer android debug
