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。
