Examples with DatabaseStorage com.microsoft.azure.mobile.utils.storage.StorageHelper.DatabaseStorage used on opensource projects

Example 1 with DatabaseStorage

use of com.microsoft.azure.mobile.utils.storage.StorageHelper.DatabaseStorage in project mobile-center-sdk-android by Microsoft.

the class StorageHelperAndroidTest method databaseStorageInMemoryDB.

/* This is a hack to test database failure by passing a weird table name which is actually valid.
       SQLite database allows to create a table that contains period (.) but it doesn't actually create the table and doesn't raise any exceptions.
       This test method will then be able to test in-memory database by accessing a table which is not created.
       Only tested on emulator so it might not work in the future or on any other devices. */
