1、获取手机本地应用。

创建AppInfo类和AppUtils类，用于接收获取到的应用列表。

Android层代码AppInfo：

public class AppInfo {
    private Drawable image;
    private String appName;
    private String packageName;

    public AppInfo() {
    }

    public Drawable getImage() {
        return image;
    }

    public void setImage(Drawable image) {
        this.image = image;
    }

    public String getAppName() {
        return appName;
    }

    public void setAppName(String appName) {
        this.appName = appName;
    }

    public String getPackageName() {
        return packageName;
    }

    public void setPackageName(String packageName) {
        this.packageName = packageName;
    }
}

Android层代码AppUtils：

public class AppUtils {
    private static final String TAG = "AppUtils";

    public static List<AppInfo> scanLocalInstallAppList(PackageManager packageManager) {
        List myAppInfos = new ArrayList();
        try {
            List packageInfos = packageManager.getInstalledPackages(0);
            for (int i = 0; i < packageInfos.size(); i++) {
                PackageInfo packageInfo = (PackageInfo) packageInfos.get(i);
                //过滤掉系统app
                if ((ApplicationInfo.FLAG_SYSTEM & packageInfo.applicationInfo.flags) != 0) {
                    continue;
                }
                AppInfo myAppInfo = new AppInfo();
                String appName = packageInfo.applicationInfo.loadLabel(packageManager).toString();
                myAppInfo.setAppName(appName);
                myAppInfo.setPackageName(packageInfo.packageName);
                if (packageInfo.applicationInfo.loadIcon(packageManager) == null) {
                    continue;
                }
                myAppInfo.setImage(packageInfo.applicationInfo.loadIcon(packageManager));
                myAppInfos.add(myAppInfo);
            }
        } catch (Exception e) {
            Log.e(TAG, "获取应用包信息失败");
        }
        return myAppInfos;
    }

}

　　Android层代码获取代码：

List<AppInfo> appInfos = AppUtils.scanLocalInstallAppList(app.getPackageManager()); //app为主activity的单例，也就是onCreate里设置app=this。
 for(int k=0;k<appInfos.size();k++)
{
      String s1 = appInfos.get(k).getAppName();//应用名
      String s2 = appInfos.get(k).getPackageName();//应用包名com.xxx.xx.xx
      Drawable dw = appInfos.get(k).getImage();//应用的icon
}    
//安卓层获取这些信息后，再传递给Unity。

　　

2、Unity调起APK的安装。

Unity代码：

设置apk的路径，假如在应用的虚拟目录下：

string apkPath  = Application.persistentDataPath + "/" + apkName;

Android代码：

public static void InstallAPK(String filePath) {
        try {
            File apkFile = new File(filePath);
            if (apkFile.exists()) {
                Intent intent = new Intent(Intent.ACTION_VIEW);
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
                    intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                    Uri contentUri = FileProvider.getUriForFile(app, app.getPackageName()+".fileprovider", apkFile);
                    intent.setDataAndType(contentUri, "application/vnd.android.package-archive");
                } else {
                    intent.setDataAndType(Uri.fromFile(apkFile), "application/vnd.android.package-archive");
                    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                }
                app.startActivity(intent);
            } else {
            }
        }
        catch (Exception ex)
        {
        }
    }

　　Android需增加配置项，写在AndroidManifest.xml里。

权限：

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

设置Provider：

${applicationId}为包名的变量，可以改写为com.xx.xx.xxx。

后面的.fileprovider需要与Android代码中的.fileprovider的名字保持一致。

provider_paths要与xml的名字保持一致。

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="${applicationId}.fileprovider"
    android:exported="false"
    android:grantUriPermissions="true">
  <meta-data
      android:name="android.support.FILE_PROVIDER_PATHS"
      android:resource="@xml/provider_paths" />
</provider>

　　

res目录下的xml文件夹下增加provider_paths.xml，内容为：

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path
        name="external_storage_root"
        path="." />
    <files-path
        name="files-path"
        path="." />
    <cache-path
        name="cache-path"
        path="." />
    <!--/storage/emulated/0/Android/data/...-->
    <external-files-path
        name="external_file_path"
        path="." />
    <!--代表app 外部存储区域根目录下的文件 Context.getExternalCacheDir目录下的目录-->
    <external-cache-path
        name="external_cache_path"
        path="." />
    <!--配置root-path。这样子可以读取到sd卡和一些应用分身的目录，否则微信分身保存的图片，就会导致 java.lang.IllegalArgumentException: Failed to find configured root that contains /storage/emulated/999/tencent/MicroMsg/WeiXin/export1544062754693.jpg，在小米6的手机上微信分身有这个crash，华为没有
-->
    <root-path
        name="root-path"
        path="" />
</paths>

 

3、启动App

//参数为app的包名，com.xx.xx.xx，如果app设置了禁止外部启动，那就无法调起。如果没有禁止外部调起，则能正常调起。    

//app为主activity的单例，也就是onCreate里设置app=this。

public static void StartIntent(String pkgName)
    {
        try {
            Log.d("启动的包名：",pkgName);
            Intent intent = app.getPackageManager().getLaunchIntentForPackage(pkgName);
            app.startActivity(intent);
        }
        catch (Exception ex)
        {
            Log.d("启动的包名1：",ex.getMessage());
        }

    }

　　

4、安装APP回调。

不止是安装有回调、替换、卸载都有回调。

Android开启监听：

    public static void ReceiverApk(){
            try{            
                installPkg = "";

                IntentFilter intentFilter = new IntentFilter();
                intentFilter.addAction(Intent.ACTION_PACKAGE_ADDED);
                intentFilter.addAction(Intent.ACTION_PACKAGE_REPLACED);
                intentFilter.addAction(Intent.ACTION_PACKAGE_REMOVED);
                intentFilter.addDataScheme("package");
                WXEntryActivity.app.registerReceiver(receiver, intentFilter);}
            catch (Exception ex)
            {}
    }

Android卸载监听：

    public static void unReceiverApk(){
        isReceiverApk=false;
        WXEntryActivity.app.unregisterReceiver(receiver);
    }

WXEntryActivity为主activity的名称。
app为主activity的单例，app=this.

Android回调：

private static BroadcastReceiver receiver=new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            Log.d("监听安装",intent.getAction().toString());
            if (intent.getAction().equals(Intent.ACTION_PACKAGE_ADDED)) {
                String packageName = intent.getData().getSchemeSpecificPart();
　　　　　　//安装
                WXEntryActivity.mUnityPlayer.UnitySendMessage("Global","UnityReceiveAndroid","apkOperation|appInstall|" + packageName);
            } else if (intent.getAction().equals(Intent.ACTION_PACKAGE_REPLACED)) {
                String packageName = intent.getData().getSchemeSpecificPart();
//                Log.e("~~~apk", packageName + "替换成功");
                WXEntryActivity.mUnityPlayer.UnitySendMessage("Global","UnityReceiveAndroid","apkOperation|appReplace|" + packageName);
                //jsbCallBack("appReplace",packageName);
            } else if (intent.getAction().equals(Intent.ACTION_PACKAGE_REMOVED)) {
                String packageName = intent.getData().getSchemeSpecificPart();
//                Log.e("~~~apk", packageName + "卸载成功");
                WXEntryActivity.mUnityPlayer.UnitySendMessage("Global","UnityReceiveAndroid","apkOperation|appRemove|" + packageName);
                //jsbCallBack("appRemove",packageName);
            }
        }
    };

WXEntryActivity.mUnityPlayer.UnitySendMessage为向Unity发送消息，通知Unity。
