java实现获取安卓设备里已安装的软件包
之前的文章向大家介绍了几个项目中常用的实用功能，那么在这篇文中，我将向大家介绍如何获取Android手机中已经安装的手机应用程序，好了，废话不多说，直接上代码
privateStringgetInstalledAppListAsString(){
PackageManagerpm=context.getPackageManager();
List<ApplicationInfo>apps=pm.getInstalledApplications(PackageManager.GET_GIDS);
StringBufferstringBuffer=newStringBuffer();
for(ApplicationInfoapp:apps){
if(pm.getLaunchIntentForPackage(app.packageName)!=null){
//appswithlauncherintent
if((app.flags&ApplicationInfo.FLAG_UPDATED_SYSTEM_APP)==1){
//updatedsystemapps
}elseif((app.flags&ApplicationInfo.FLAG_SYSTEM)==1){
//systemapps
}else{
//userinstalledapps
stringBuffer.append(app.packageName).append(';');
}
}
}
returnstringBuffer.toString();
}
下面我们看看具体如何获取各个应用的相关信息呢
packagecn.lyz.mobilesafe.domain;
importandroid.graphics.drawable.Drawable;
/**

*/
publicclassAppInfo{
//图标
privateDrawableapp_icon;
//应用名称
privateStringapp_name;
//应用版本号
privateStringapp_version;
//应用包名
privateStringpackagename;
//是否是用户app
privatebooleanisUserApp;
publicAppInfo(){
super();
//TODOAuto-generatedconstructorstub
}
publicAppInfo(Drawableapp_icon,Stringapp_name,Stringapp_version,
Stringpackagename){
super();
this.app_icon=app_icon;
this.app_name=app_name;
this.app_version=app_version;
this.packagename=packagename;
}
publicAppInfo(Drawableapp_icon,Stringapp_name,Stringapp_version,
Stringpackagename,booleanisUserApp){
super();
this.app_icon=app_icon;
this.app_name=app_name;
this.app_version=app_version;
this.packagename=packagename;
this.isUserApp=isUserApp;
}
publicDrawablegetApp_icon(){
returnapp_icon;
}
publicvoidsetApp_icon(Drawableapp_icon){
this.app_icon=app_icon;
}
publicStringgetApp_name(){
returnapp_name;
}
publicvoidsetApp_name(Stringapp_name){
this.app_name=app_name;
}
publicStringgetApp_version(){
returnapp_version;
}
publicvoidsetApp_version(Stringapp_version){
this.app_version=app_version;
}
publicStringgetPackagename(){
returnpackagename;
}
publicvoidsetPackagename(Stringpackagename){
this.packagename=packagename;
}
publicbooleanisUserApp(){
returnisUserApp;
}
publicvoidsetUserApp(booleanisUserApp){
this.isUserApp=isUserApp;
}
@Override
publicStringtoString(){
return"AppInfo[app_icon="+app_icon+",app_name="+app_name
+",app_version="+app_version+",packagename="
+packagename+",isUserApp="+isUserApp+"]";
}
}
