This app provides monitoring and information features for the common freifunk user and the technical stuff of a freifunk community.
Code base is taken from a TUM Practical Course project and added here to see if Freifunk Altdorf can use it.

|
* |
|
* ```xml |
|
* <manifest> |
|
* <application> |
|
* <provider |
|
* android:name="com.facebook.react.modules.blob.BlobProvider" |
|
* android:authorities="@string/blob_provider_authority" |
|
* android:exported="false" |
|
* /> |
|
* </application> |
|
* </manifest> |
|
* ``` |
|
* And then define the `blob_provider_authority` string in `res/values/strings.xml`. |
|
* Use a dotted name that's entirely unique to your app: |
|
* |
|
* ```xml |
|
* <resources> |
|
* <string name="blob_provider_authority">your.app.package.blobs</string> |
|
