在 api 11 之前使用 AbstractThreadedSyncAdapter

Question

如何为低于API-11的minSDK使用AbstractThreadedSyncAdapter？以下构造函数抱怨需要 API-11.

public DogSyncAdapter(Context context, boolean autoInitialize, boolean allowParallelSyncs) {
    super(context, autoInitialize, allowParallelSyncs);
  }

Answer 1

正如文档中所说：

Api 5 级：

public AbstractThreadedSyncAdapter (Context context, boolean autoInitialize)

Api 11 级：

public AbstractThreadedSyncAdapter (Context context, boolean autoInitialize, boolean allowParallelSyncs)

所以你只需要实现两个构造函数，然后调用一个或另一个：

if (sSyncAdapter == null) {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
                    sSyncAdapter = new NotificationsSyncAdapter(getApplicationContext(), true, true);
                } else {
                    sSyncAdapter = new NotificationsSyncAdapter(getApplicationContext(), true);
                }
            }
