java - 找不到处理 Intent {act=android.settings.action.MANAGE_WRITE_SETTINGS

Question

当我这样做时我的应用程序崩溃了:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    if (Settings.System.canWrite(ListOfTerminalsActivity.this)) {
         // Do stuff here
     } else {
         Intent intent = new Intent(android.provider.Settings.ACTION_MANAGE_WRITE_SETTINGS);
         intent.setData(Uri.parse("package:" + getPackageName()));
         intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
         startActivity(intent);
     }
}

它发生在 ZUK Z2 的 API 23 上，这是日志；

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.settings.action.MANAGE_WRITE_SETTINGS dat=package:pl.teminalmobile flg=0x10000000 }

这并没有发生，我的应用程序也没有崩溃，例如在设备 samsung s5 API 23、samsung s7 API 24 上

引用 the documentation for ACTION_MANAGE_WRITE_SETTINGS :

In some cases, a matching Activity may not exist, so ensure you safeguard against this.

因此，将您的 startActivity() 调用包装在 try/catch block 中，如果您收到 ActivityNotFoundException，做点别的。例如，您可以尝试相同的 Intent 操作但不包括 package Uri。
