Unity3D调用Android功能与组件(10.1):应用自启动
前言
我在Unity3D调用Android功能与组件(十)—BroadcastReceiver中介绍了如何使用Unity接入广播。
然而很多没有做过Android的小伙伴却表示

那我也只能

其实,广播作为Android四大组件之一,其妙用之处太多太多。你可以用来做应用自启动,也可用来做智能网络检测、电量优化大师、定位器等等。
秉着让大家少走一步弯路的原则,我还是在这里单独发一篇帖子与大家分享。感兴趣的小伙伴还是建议多看看Unity3D调用Android功能与组件(十)—BroadcastReceiver这篇,因为有更高的自由度任你发挥。
正文:
1.首先申请相应权限
在AndroidMenifest.xml中添加下列权限,可根据自己需要酌情增减
< uses-permission android:name = "android.permission.RECEIVE_BOOT_COMPLETED" /> < uses-permission android:name = "android.permission.ACCESS_WIFI_STATE" /> < uses-permission android:name = "android.permission.WRITE_EXTERNAL_STORAGE" /> < uses-permission android:name = "android.permission.READ_PHONE_STATE" /> < uses-permission android:name = "android.permission.READ_EXTERNAL_STORAGE" /> < uses-permission android:name = "android.permission.BIND_ACCESSIBILITY_SERVICE" /> < uses-permission android:name = "android.permission.BIND_SCREENING_SERVICE" /> < uses-permission android:name = "android.permission.RECEIVE_USER_PRESENT" /> |
温馨提示:请妥善使用权限,坚决不申请用不到的权限
2.添加广播接收
< receiver android:name = ".SelfWakeBroadcastReceiver" android:process = ":remote" > < intent-filter android:priority = "90000" > < action android:name = "android.intent.action.BOOT_COMPLETED" /> < action android:name = "android.net.conn.CONNECTIVITY_CHANGE" /> < action android:name = "android.intent.action.PHONE_STATE" /> < action android:name = "android.intent.action.DATE_CHANGED" /> < action android:name = "android.intent.action.ACTION_POWER_CONNECTED" /> < action android:name = "android.intent.action.SCREEN_OFF" /> < action android:name = "android.intent.action.SCREEN_ON" /> < category android:name = "android.intent.category.HOME" /> < action android:name = "android.intent.action.USER_PRESENT" /> </ intent-filter > </ receiver > |
在AndroidMenifest.xml中把上面的代码加到Application标签里面。
3.Java源码及打包
package com.unity3d.player; import java.util.List; import android.content.BroadcastReceiver; import android.content.ComponentName; import android.content.Context; import android.content.Intent; import android.content.IntentFilter; import android.content.pm.ApplicationInfo; import android.content.pm.PackageInfo; import android.content.pm.PackageManager; import android.content.pm.PackageManager.NameNotFoundException; import android.content.pm.ResolveInfo; import android.util.Log; /** * Created by User on 2016/11/19. */ public class SelfWakeBroadcastReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Log.v( "SelfWakeBroadcast" , "has Receive a broadcast" ); RunApp(context, "com.hhu.virtualhair" ); //TODO 换成自己的包名 } public void registerScreenActionReceiver(Context mContext) { IntentFilter filter = new IntentFilter(); filter.addAction(Intent.ACTION_SCREEN_OFF); filter.addAction(Intent.ACTION_SCREEN_ON); filter.addAction(Intent.ACTION_USER_PRESENT); mContext.registerReceiver(SelfWakeBroadcastReceiver. this , filter); } private void RunApp(Context context,String packageName) { PackageInfo pi; try { pi = context.getPackageManager().getPackageInfo(packageName, 0 ); Intent resolveIntent = new Intent(Intent.ACTION_MAIN, null ); resolveIntent.setPackage(pi.packageName); PackageManager pManager = context.getPackageManager(); List<ResolveInfo> apps = pManager.queryIntentActivities( resolveIntent, 0 ); ResolveInfo ri = apps.iterator().next(); if (ri != null ) { String className = ri.activityInfo.name; Intent intent = new Intent(Intent.ACTION_MAIN); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); ComponentName cn = new ComponentName(ri.activityInfo.packageName, className); intent.setComponent(cn); context.startActivity(intent); } } catch (NameNotFoundException e) { e.printStackTrace(); } } } |
把上述Java代码中的//TODO 换成自己的包名处的报名替换为自己应用的报名;
将上述代码打包成.jar;
把打包好的jar文件放到Unity的/Assets/Plugins/Android/文件夹下。
4.大功告成!
发布你的软件或游戏,享受自启的快感!

本帖子内容实际上是2016年的一个回答,由于时间比较久远,随着Android系统的升级,可能某些小伙伴使用本帖子提供的教程会出问题,MemoryC也没来得及去测试与更正。
最近交流群里三位小伙伴一起探讨了一个方案,我把他们得出的教程粘在这里,有需要的码友可参考下。
