下面列出了怎么用android.content.SyncStatusObserver的API类实例代码及写法，或者点击链接到github查看源代码。
@Override
public Object addStatusChangeListener(int mask, SyncStatusObserver callback) {
return ContentResolver.addStatusChangeListener(mask, callback);
}
@Override
public Object addStatusChangeListener(int mask, SyncStatusObserver callback) {
return ContentResolver.addStatusChangeListener(mask, callback);
}
@Override
public Object addStatusChangeListener(int mask, SyncStatusObserver callback) {
return ContentResolver.addStatusChangeListener(mask, callback);
}
Object addStatusChangeListener(int mask, SyncStatusObserver callback); Object addStatusChangeListener(int mask, SyncStatusObserver callback); Object addStatusChangeListener(int mask, SyncStatusObserver callback);
