Question

我正在从onServiceConnected()的{{1}}方法开始一项活动。

我成功启动了AccessibilityService，但无法从中启动设备管理意图。

我调试了我的应用程序，服务已成功启动，并且AccessibilityService也称为onServiceConnected()的执行也没有崩溃，但DeviceAdmin意图仍未启动。

callDeviceAdmin()

更新

public class AccessibilityEventService extends AccessibilityService {

    public static final int REQUEST_CODE_FOR_ACTIVE_DEVICE_ADMIN = 100;

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {

    }

    @Override
    public void onInterrupt() {
        Log.d("TAG", "EXECUTE ON Interrupt");
    }

    @Override
    protected void onServiceConnected() {
        callDeviceAdmin();
    }


    private void callDeviceAdmin(){
        ComponentName mComponentName;
        DevicePolicyManager mDevicePolicyManager;
        mDevicePolicyManager = (DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE);
        mComponentName = new ComponentName(this, AdminReceiver.class);

        try{
            boolean isAdmin = mDevicePolicyManager.isAdminActive(mComponentName);
            if (!isAdmin) {
                Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
                intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, mComponentName);
                intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION, "SaferCell wants device Administrator access");
                getApplicationContext().startActivity(intent);
            }
        } catch (Exception e) {
            Log.d("onAccessibilityEvent", e.getMessage());
            e.printStackTrace();
        }

    }
}

您也可以尝试使用代码，但是我创建了一个演示可访问性服务来尝试此操作，并且运行良好。

您必须添加Intent标志，因为要从Activity上下文外部启动活动需要FLAG_ACTIVITY_NEW_TASK标志。

 public class AccessibilityServiceDemo extends AccessibilityService {
        @Override
        public void onAccessibilityEvent(AccessibilityEvent accessibilityEvent) {

        }

        @Override
        public void onInterrupt() {

        }

        @Override
        protected void onServiceConnected() {
            super.onServiceConnected();
            System.out.println("onServiceConnected");
            Intent intent = new Intent().setComponent(new ComponentName("com.android.settings", "com.android.settings.DeviceAdminSettings"));
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(intent);

        }
    }

无法从AccessibilityService的onServiceConnected（）启动Activity（intent）
