android系统广播有哪些呢，本文做一个整理。

Intent类里面有系统广播的名称的定义，系统广播都会有下面这样的注释

* This is a protected intent that can only be sent by the system.

有这样注释的广播的定义一共有52个，如下面所示：

public static final String ACTION_INSTALL_EPHEMERAL_PACKAGE
            = "android.intent.action.INSTALL_EPHEMERAL_PACKAGE";
public static final String ACTION_RESOLVE_EPHEMERAL_PACKAGE
            = "android.intent.action.RESOLVE_EPHEMERAL_PACKAGE";

public static final String ACTION_PACKAGES_UNSUSPENDED = "android.intent.action.PACKAGES_UNSUSPENDED";
public static final String ACTION_UID_REMOVED = "android.intent.action.UID_REMOVED";
public static final String ACTION_PACKAGE_FIRST_LAUNCH = "android.intent.action.PACKAGE_FIRST_LAUNCH";
public static final String ACTION_PACKAGE_NEEDS_VERIFICATION = "android.intent.action.PACKAGE_NEEDS_VERIFICATION";
public static final String ACTION_PACKAGE_VERIFIED = "android.intent.action.PACKAGE_VERIFIED";
public static final String ACTION_INTENT_FILTER_NEEDS_VERIFICATION = "android.intent.action.INTENT_FILTER_NEEDS_VERIFICATION";
public static final String ACTION_EXTERNAL_APPLICATIONS_AVAILABLE =
        "android.intent.action.EXTERNAL_APPLICATIONS_AVAILABLE";

        "android.intent.action.EXTERNAL_APPLICATIONS_UNAVAILABLE";
public static final String ACTION_CONFIGURATION_CHANGED = "android.intent.action.CONFIGURATION_CHANGED";
public static final String ACTION_LOCALE_CHANGED = "android.intent.action.LOCALE_CHANGED";
public static final String ACTION_BATTERY_CHANGED = "android.intent.action.BATTERY_CHANGED";
    public static final String ACTION_BATTERY_LOW = "android.intent.action.BATTERY_LOW";
    public static final String ACTION_BATTERY_OKAY = "android.intent.action.BATTERY_OKAY";
    public static final String ACTION_POWER_CONNECTED = "android.intent.action.ACTION_POWER_CONNECTED";

public static final String ACTION_REQUEST_SHUTDOWN = "android.intent.action.ACTION_REQUEST_SHUTDOWN";
public static final String ACTION_DEVICE_STORAGE_LOW = "android.intent.action.DEVICE_STORAGE_LOW";
public static final String ACTION_DEVICE_STORAGE_OK = "android.intent.action.DEVICE_STORAGE_OK";
public static final String ACTION_DEVICE_STORAGE_FULL = "android.intent.action.DEVICE_STORAGE_FULL";
public static final String ACTION_DEVICE_STORAGE_NOT_FULL = "android.intent.action.DEVICE_STORAGE_NOT_FULL";
public static final String ACTION_AIRPLANE_MODE_CHANGED = "android.intent.action.AIRPLANE_MODE";
public static final String ACTION_ADVANCED_SETTINGS_CHANGED
            = "android.intent.action.ADVANCED_SETTINGS";
public static final String ACTION_APPLICATION_RESTRICTIONS_CHANGED =
            "android.intent.action.APPLICATION_RESTRICTIONS_CHANGED";
public static final String ACTION_NEW_OUTGOING_CALL =
            "android.intent.action.NEW_OUTGOING_CALL";
public static final String ACTION_REBOOT =
            "android.intent.action.REBOOT";
public static final String ACTION_IDLE_MAINTENANCE_START =
            "android.intent.action.ACTION_IDLE_MAINTENANCE_START";
public static final String ACTION_IDLE_MAINTENANCE_END =
            "android.intent.action.ACTION_IDLE_MAINTENANCE_END";
public static final String ACTION_MEDIA_RESOURCE_GRANTED =
            "android.intent.action.MEDIA_RESOURCE_GRANTED";
public static final String ACTION_DYNAMIC_SENSOR_CHANGED = 
            "android.intent.action.DYNAMIC_SENSOR_CHANGED";

正如注释所描述的那样，这些系统广播只能由系统发出，第三方应用是无法发送系统广播的，第三方应用如果尝试发送系统广播，会报下面的错误：

java.lang.SecurityException: Permission Denial: not allowed to send broadcast android.intent.action.BOOT_COMPLETED from pid=31204, uid=10076
        at android.os.Parcel.readException(Parcel.java:1683)
        at android.os.Parcel.readException(Parcel.java:1636)
        at android.app.ActivityManagerProxy.broadcastIntent(ActivityManagerNative.java:3609)
        at android.app.ContextImpl.sendBroadcast(ContextImpl.java:893)
        at android.content.ContextWrapper.sendBroadcast(ContextWrapper.java:421)

该异常是由frameworks\base\services\core\java\com\android\server\am\ActivityManagerService.java的broadcastIntentLocked方法所发出的：

// First line security check before anything else: stop non-system apps from
        // sending protected broadcasts.
        if (!isCallerSystem) {
            if (isProtectedBroadcast) {
                String msg = "Permission Denial: not allowed to send broadcast "
                        + action + " from pid="
                        + callingPid + ", uid=" + callingUid;
                Slog.w(TAG, msg);
                throw new SecurityException(msg);
            }
            。。。。。。
        }

作为补充，下面五个系统广播是只能动态注册而不支持静态注册：

android.intent.action.SCREEN_ON
android.intent.action.SCREEN_OFF
android.intent.action.BATTERY_CHANGED
android.intent.action.CONFIGURATION_CHANGED
android.intent.action.TIME_TICK
