当设备在 Android 上启动时，我一直在尝试测试一项服务，但我无法让它工作。 我正在尝试使用 CMD 中的此命令启动它:

(在 ..\AppData\Local\Android\sdk\platform-tools 中)

adb shell am broadcast -a android.intent.action.BOOT_COMPLETED

或

adb shell am broadcast -a android.intent.action.BOOT_COMPLETED -c android.intent.category.HOME -n net.fstab.checkit_android/.MyReceiver

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.tabache.sciopero">

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

            </intent-filter>
        </receiver>

            android:value="@integer/google_play_services_version" />
    </application>

</manifest>

我的接收器类是这样的:

public class MyReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    System.out.println("MyReceiver !!!!");
    Intent startServiceIntent = new Intent(context, MioServizio.class);

context.startService(startServiceIntent);
}
}

我的 dos 命令的答案是这样的:

Broadcasting: Intent { act=android.intent.action.BOOT_COMPLETED cat=[android.intent.category.HOME] cmp=net.fstab.checkit_android/.MyReceiver }
java.lang.SecurityException: Permission Denial: not allowed to send broadcast android.intent.action.BOOT_COMPLETED from pid=3715, uid=2000
        at android.os.Parcel.readException(Parcel.java:1683)
        at android.os.Parcel.readException(Parcel.java:1636)

        at com.android.internal.os.RuntimeInit.nativeFinishInit(NativeMethod)
        at com.android.internal.os.RuntimeInit.main(RuntimeInit.java:262)

为什么我有这个错误“java.lang.SecurityException: Permission Denial”？

最佳答案

我有同样的问题并通过这个解决:

 Try restarting ADB in root mode: adb root

然后像这样广播 BOOT_COMPLETED

 adb shell am broadcast -a android.intent.action.BOOT_COMPLETED 
 -p yourpackage.app
