我试过的建议在这里,建议在此情况下,建议在这里,我已经在我的基本活动注释掉onAttachedToWindow().我有两个活动继承自这个类BaseActivity.一个运行,一个不运行.有什么区别？我的目标SDK是19; 将它改为12没有区别.这是我的onCreate for BaseActivity:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    super.onAttachedToWindow();
    super.onCreate(savedInstanceState);

    ....
    }

当导航到第二个活动时,单步执行代码,它会通过onCreate(),onResume(),然后崩溃.

可能是什么问题呢？

我试图阻止状态栏扩展,我已经使用了一些人们试图覆盖主页按钮的例子.所有解决方案都指向使用WindowManager.LayoutParams.TYPE_KEYGUARD,我在这里读到,如果使用TYPE_KEYGUARD,最小目标必须小于14.不推荐使用TYPE_KEYGUARD,所以我还需要解决这个问题.它已完全从SDK 21中删除.

问题:什么是变通方法所以我可以覆盖状态栏并将目标构建保持为19？

我有一个像这样的构建项目:

android {
   compileSdkVersion 17
   buildToolsVersion "21.1.2"

   defaultConfig {
      applicationId "com.mycompany.ediary"
      minSdkVersion 12
      targetSdkVersion 12
   }

   buildTypes {
      release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
      }
   }
}

我试过这里的建议无济于事.我希望targetSdkVersion为19,但如果我将其更改为19,我会得到IllegalArgumentException.堆栈跟踪:
