平台
RK3399 + Android 8.1
问题
在旧SDK使用的关机接口在8.1上测试不可用, 代码如下:
//shutdown now String action = "android.intent.action.ACTION_REQUEST_SHUTDOWN"; Intent shutdown = new Intent(action); shutdown.putExtra("android.intent.extra.KEY_CONFIRM", false); shutdown.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); try { startActivity(shutdown); finish(); }catch(Exception e){ e.printStackTrace(); }
执行时发现找不到 activity.
原因
|-- frameworks/base/core/java/android/content/Intent.java
旧SDK:
public static final String ACTION_REQUEST_SHUTDOWN = "android.intent.action.ACTION_REQUEST_SHUTDOWN";
新SDK:
public static final String ACTION_REQUEST_SHUTDOWN = "com.android.internal.intent.action.REQUEST_SHUTDOWN";
Action值变了, 新代码如下
//shutdown now String action = "com.android.internal.intent.action.REQUEST_SHUTDOWN"; if(Build.VERSION.SDK_INT <= Build.VERSION_CODES.N){ action = "android.intent.action.ACTION_REQUEST_SHUTDOWN"; } Intent shutdown = new Intent(action); shutdown.putExtra("android.intent.extra.KEY_CONFIRM", false); shutdown.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); try { startActivity(shutdown); finish(); }catch(Exception e){ e.printStackTrace(); }
