2.解决正常发广播的问题
//frameworks/base/services/core/java/com/android/server/am/ActivityManagerService.java
private void checkBroadcastFromSystem(Intent intent, ProcessRecord callerApp,
String callerPackage, int callingUid, boolean isProtectedBroadcast, List receivers) {
if ((intent.getFlags() & Intent.FLAG_RECEIVER_FROM_SHELL) != 0) {
// Don't yell about broadcasts sent via shell
return;
}
final String action = intent.getAction();
if (isProtectedBroadcast
|| "com.android.my_install_apk_broadcat".equals(action) //添加这个判断
|| Intent.ACTION_CLOSE_SYSTEM_DIALOGS.equals(action)
|| Intent.ACTION_DISMISS_KEYBOARD_SHORTCUTS.equals(action)
|| Intent.ACTION_MEDIA_BUTTON.equals(action)
|| Intent.ACTION_MEDIA_SCANNER_SCAN_FILE.equals(action)
|| Intent.ACTION_SHOW_KEYBOARD_SHORTCUTS.equals(action)
|| Intent.ACTION_MASTER_CLEAR.equals(action)
|| Intent.ACTION_FACTORY_RESET.equals(action)
|| AppWidgetManager.ACTION_APPWIDGET_CONFIGURE.equals(action)
|| AppWidgetManager.ACTION_APPWIDGET_UPDATE.equals(action)
|| LocationManager.HIGH_POWER_REQUEST_CHANGE_ACTION.equals(action)
|| TelephonyManager.ACTION_REQUEST_OMADM_CONFIGURATION_UPDATE.equals(action)
|| SuggestionSpan.ACTION_SUGGESTION_PICKED.equals(action)
|| AudioEffect.ACTION_OPEN_AUDIO_EFFECT_CONTROL_SESSION.equals(action)
|| AudioEffect.ACTION_CLOSE_AUDIO_EFFECT_CONTROL_SESSION.equals(action)) {
// Broadcast is either protected, or it's a public action that
// we've relaxed, so it's fine for system internals to send.
return;
}
......
}
3.调用安装器
//FuncTools.java
@SuppressWarnings("deprecation")
public void directInstall(String path, boolean install, final boolean openWhenInstalled) {
try {
if (!TextUtils.isEmpty(path)) {
IPackageManager mPm = IPackageManager.Stub.asInterface(ServiceManager.getService("package"));
if (install) { //静默安装
Installer.silentInstallApk(mContext,path,UserHandle.myUserId(),openWhenInstalled);
} else { //静默卸载
IPackageDeleteObserver observer = new IPackageDeleteObserver.Stub() {
@Override
public void packageDeleted(String packageName, int returnCode) throws RemoteException {
android.util.Log.d(TAG, "directInstall...packageDeleted...");
}
};
mPm.deletePackageAsUser(path, PackageManager.VERSION_CODE_HIGHEST, observer, UserHandle.myUserId(),
PackageManager.DELETE_ALL_USERS);
}
}
} catch (Exception e) {
e.printStackTrace();
android.util.Log.e(TAG, "directInstall error:path=" + path + ",,install=" + install + ",,open=" + openWhenInstalled+",e="+e);
}
}
4.广播接收安装信息
//MainActivity.java
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//注册动态广播
IntentFilter filter = new IntentFilter();
filter.addAction("com.android.my_install_apk_broadcat");
registerReceiver(myInstallReceiver, filter);
}
//广播监听
BroadcastReceiver myInstallReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
Log.d(TAG,"[MainActivity] onReceive...action="+intent.getAction());
if ("com.android.my_install_apk_broadcat".equals(intent.getAction())) {
String pkgName = intent.getStringExtra(PackageInstaller.EXTRA_PACKAGE_NAME);
String statusMsg = intent.getStringExtra(PackageInstaller.EXTRA_STATUS_MESSAGE);
int status = intent.getIntExtra(PackageInstaller.EXTRA_STATUS, 0);
Log.i(TAG, "install_apk_broadcat,,,pkgName=" + pkgName + ",,statusMsg=" + statusMsg + ",,status="
+ status);
}
}
};
