IssueTracker

We don't support cross-process invalidations yet.

At least , add a "refresh all observables" function to alpha4 ? i am trying to implement it by myself with your InvalidationTracker class

Okey, I made it and created a method to invalidate all observables below;

private void refreshAllLiveData() {
        AppDataBase YOUR_DATABASE_WHICH_YOU_BUILD =  .....
        SupportSQLiteDatabase writableDatabase = YOUR_DATABASE_WHICH_YOU_BUILD.getOpenHelper().getWritableDatabase();
        //get the database count;
        Cursor cursor = writableDatabase.query("SELECT count(*) FROM sqlite_master WHERE type = 'table' AND name != 'android_metadata' AND name != 'room_master_table';");
        int tableCount = 0;
        while(cursor.moveToNext()) {
            tableCount = cursor.getInt(0);
        }

        for (int i = 0; i < tableCount; i++) {
            //update version table with the incremented count because room modification log stores tables with ids instead of names
            writableDatabase.execSQL("INSERT OR REPLACE INTO room_table_modification_log VALUES(null, "+(i)+")");
        }
        YOUR_DATABASE_WHICH_YOU_BUILD.getInvalidationTracker().refreshVersionsAsync();
    }

This is a workaroud for refreshing all live datas, I still prefer to use a proper API you implemented.

Thanx

Cross process invalidation is now support in Room 2.1.0 with the enableMultiInstanceInvalidation() API.

#5 I guess he means this, although it only lets you add classes but not java files:
