如何在手机重启或手动关闭或开启电源后启动发布活动

我试过下面的代码，但它只用于解锁手机，但我也想完成手动启动或重启手机。

下面是代码

application.class

public class MyApplication extends Application {
    public static SharedPreferences preferences;
    public static SharedPreferences.Editor editor;
    public static String PASSWORD = "password";
    public static String IS_SET = "nothing";
    public static String MYPREF = "mypref";
    public String TAG = getClass().getName();

    @Override
    protected void attachBaseContext(Context context) {
        super.attachBaseContext(context);
        MultiDex.install(this);
    }

    @Override
    public void onCreate() {
        super.onCreate();
        init();  
   }

    public void init() {
        preferences = getSharedPreferences(MYPREF, 0);
        editor = preferences.edit();
        startService(new Intent(getBaseContext(), ScreenReceiver.class));

    }
}

ScreenReceiver.class

public class ScreenReceiver extends BroadcastReceiver {
     SharedPreferences preferences;

        @Override
        public void onReceive(Context context, Intent intent) {
            System.out.println(intent.getAction());
            preferences = context.getSharedPreferences(MYPREF, 0);
            if (preferences != null) {
                String lock = preferences.getString(IS_SET, null);
                if (lock != null) {
                    if (lock.equals("passcode")) {
                        gotopasslock(context, intent);

                    } else {
                        gotopatternlock(context, intent);
                    }
                }
            }
        }
        public void gotopasslock(Context context, Intent intent) {
            if (intent.getAction().equals(Intent.ACTION_USER_PRESENT)) {
                Intent intent1 = new Intent(context, Main.class);
                intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                context.startActivity(intent1);
            } else if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
                Intent myStarterIntent = new Intent(context, Main.class);
                myStarterIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                context.startActivity(myStarterIntent);
            }
        }

        public void gotopatternlock(Context context, Intent intent) {

            if (intent.getAction().equals(Intent.ACTION_USER_PRESENT)) {
                Intent intent1 = new Intent(context, PatternLock.class);
                intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                context.startActivity(intent1);
            } else if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
                Intent myStarterIntent = new Intent(context, PatternLock.class);
                myStarterIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                context.startActivity(myStarterIntent);
            }
        }
    }

Main.class

public class Main extends AppCompatActivity {
    private PinLockView mPinLockView;
    private IndicatorDots mIndicatorDots;
    private String TAG = getClass().getName();
    String oldPassword = "";
    String newPassword = "";
    SharedPreferences preferences;
    SharedPreferences.Editor editor;


    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        // getSupportActionBar().hide();
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_xml);

Answer 1

缺少意图行动。

要在重新启动后启动Android活动，请添加以下行的的AndroidManifest.xml

第1步

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

第2步：

<receiver android:name=".receiver.ScreenReceiver" android:label="ScreenReceiver"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> </intent-filter> <intent-filter> <action android:name="android.intent.action.USER_PRESENT" </intent-filter> </receiver>

注意：

尝试进行代码清理

电话重启后启动活动或手动关闭或打开电源
