关于从设备中的所有应用程序（包括systemapps和userapps）获取appName，我遇到了一个严重的问题。如果数量太多，就会出现问题-在我的Samsung S7 userapps和systemapps中总和为433。
似乎可以限制对ApplicationInfo的方法“ loadLabel”进行的调用次数。例如-如果我仅从systemapps获取名称，则工作正常-如果我仅从userapps获取名称，则效果相同。但是，如果同时获取userapp和systemapp，则App崩溃-尤其是当我有一个进度条显示正在加载时。
这是JVM外部的一个异常（EGL似乎很生气），但是在致命信号出现之前，您可以看到有关打开太多文件的消息，并且无法获得resourceID。等
我的问题是-有一种简单的方法可以使它起作用吗？
我使用asynctask，这是 doInBackground
的代码段@Override
public String doInBackground(String ... params) {
//commenting out one the calls makes everything work
//if you call both the app crashces
appInfoRetriever.parseUserApps();
appInfoRetriever.parseSystemApps();
return "done! :)";
}
这是appInfoRetriever
public AppInfoRetriever_(Context context) {
this.context = context;
packageManager = context.getPackageManager();
packageInfoList = getInstalledPackages(context, PackageManager.GET_META_DATA);
split();
}
private void split() {
for(PackageInfo pInfo: packageInfoList) {
if(isSystemApp(pInfo.packageName))
packageInfoListS.add(pInfo);
else
packageInfoListU.add(pInfo);
}
}
public void parseUserApps() {
packageManager = context.getPackageManager();
for (PackageInfo pInfo: packageInfoListU) {
ApplicationInfo info = pInfo.applicationInfo;
parseHelper(info);
AppDataHolder appDataHolder = parseHelper(info);
appUserDataHolderList.add(appDataHolder);
}
}
public void parseSystemApps() {
packageManager = context.getPackageManager();
for (PackageInfo pInfo: packageInfoListS) {
ApplicationInfo info = pInfo.applicationInfo;
AppDataHolder appDataHolder = parseHelper(info);
appSystemDataHolderList.add(appDataHolder);
}
}
private AppDataHolder parseHelper(ApplicationInfo info) {
//namn
String appName = "";
try {
appName = info.loadLabel(packageManager).toString();
} catch(Exception e) {
System.err.println("UNDANTAG loadLabel(PackageManager)");
e.printStackTrace();
appName = "null";
}
AppDataHolder appDataHolder = new AppDataHolder();
appDataHolder.setAppName(appName);
//appDataHolderList.add(appDataHolder);
return appDataHolder;
}
这是关键行，对很多电话都是不容忍的
appName = info.loadLabel(packageManager).toString();
