Initialize global context before MainApp.onCreate()

This could fix #3901 and possibly some other issues.

Can I ask why not a module and then provideContext which can be injected everywhere to get application-wide context?

[ezaquarii]

getApplicationContext() is null, as the app context is set somewhere between Application.attachBaseContext() and Application.onCreate(). However, because there is only 1 instance of MainApp, there is no leak, so no worries.

Once the base context is attached, the context is basically functional, with some obscure exceptions around Looper and whatnot. Those should be fully initialized before ContentProvider.onCreate() kicks in.

It is already done.

android/src/main/java/com/nextcloud/client/di/AppModule.java

Line 55 in d544fa5

Contextcontext(Applicationapplication) {

However, large portions of the code still call to MainApp.getAppContext() either directly or indirectly via other helpers and it will be a long march to fix this.

The best we can do in this situation is to provide them a valid reference. This can't be worse than NPE. :)
