android - Android 1.6 上的 java.lang.VerifyError 和 getActionBar()

Question

在我的应用程序中，我使用了这段代码:

@TargetApi(14)
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    if(android.os.Build.VERSION.SDK_INT>=14) {
        getActionBar().setHomeButtonEnabled(false);
    }

}

但是当我在 Android 1.6 的模拟器中运行它时，我得到了这个错误:

当我删除行 getActionBar().setHomeButtonEnabled(false);它工作正常。如何在不删除此行的情况下修复它？

Answer 1

使用 android-support-v4.jar 就像在隐藏它之后添加 ActionBar 一样。

希望你用过actiobarShareLock对于 < 11 API。
