最近在android 4.0.4系统下实现apk的静默安装和启动的功能，这里和大家分享一下，希望能有所帮助。

源码如下：

[java] view plain copy

importjava.io.DataOutputStream;
importjava.io.File;
importjava.io.IOException;
importjava.io.OutputStream;
importjava.util.ArrayList;
importjava.util.List;
importandroid.content.Context;
importandroid.content.Intent;
importandroid.content.pm.ActivityInfo;
importandroid.content.pm.PackageInfo;
importandroid.content.pm.PackageManager;
importandroid.content.pm.ResolveInfo;
publicclassInstallApkUtils{
publicstaticvoidinstallAndStartApk(finalContextcontext,finalStringapkPath){
if((apkPath==null)||(context==null)){
return;
}
Filefile=newFile(apkPath);
if(file.exists()==false){
return;
}
newThread(){
publicvoidrun(){
StringpackageName=getUninstallApkPackageName(context,apkPath);
if(silentInstall(apkPath)){
List<ResolveInfo>matches=findActivitiesForPackage(context,packageName);
if((matches!=null)&&(matches.size()>0)){
ResolveInforesolveInfo=matches.get(0);
ActivityInfoactivityInfo=resolveInfo.activityInfo;
startApk(activityInfo.packageName,activityInfo.name);
}
}
};
}.start();
}
publicstaticStringgetUninstallApkPackageName(Contextcontext,StringapkPath){
StringpackageName=null;
if(apkPath==null){
returnpackageName;
}
PackageManagerpm=context.getPackageManager();
PackageInfoinfo=pm.getPackageArchiveInfo(apkPath,
PackageManager.GET_ACTIVITIES);
if(info==null){
returnpackageName;
}
packageName=info.packageName;
returnpackageName;
}
publicstaticList<ResolveInfo>findActivitiesForPackage(Contextcontext,StringpackageName){
finalPackageManagerpm=context.getPackageManager();
finalIntentmainIntent=newIntent(Intent.ACTION_MAIN,null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
mainIntent.setPackage(packageName);
finalList<ResolveInfo>apps=pm.queryIntentActivities(mainIntent,0);
returnapps!=null?apps:newArrayList<ResolveInfo>();
}
publicstaticbooleansilentInstall(StringapkPath){
Stringcmd1="chmod777"+apkPath+"\n";
Stringcmd2="LD_LIBRARY_PATH=/vendor/lib:/system/libpminstall-r"+apkPath+"\n";
returnexecWithSID(cmd1,cmd2);
}
privatestaticbooleanexecWithSID(String...args){
booleanisSuccess=false;
Processprocess=null;
OutputStreamout=null;
try{
process=Runtime.getRuntime().exec("su");
out=process.getOutputStream();
DataOutputStreamdataOutputStream=newDataOutputStream(out);
for(Stringtmp:args){
dataOutputStream.writeBytes(tmp);
}
dataOutputStream.flush();//提交命令
dataOutputStream.close();//关闭流操作
out.close();
isSuccess=waitForProcess(process);
}catch(IOExceptione){
e.printStackTrace();
}
returnisSuccess;
}
publicstaticbooleanstartApk(StringpackageName,StringactivityName){
booleanisSuccess=false;
Stringcmd="amstart-n"+packageName+"/"+activityName+"\n";
try{
Processprocess=Runtime.getRuntime().exec(cmd);
isSuccess=waitForProcess(process);
}catch(IOExceptione){
NLog.i(TAG,e.getMessage());
e.printStackTrace();
}
returnisSuccess;
}
privatestaticbooleanwaitForProcess(Processp){
booleanisSuccess=false;
intreturnCode;
try{
returnCode=p.waitFor();
switch(returnCode){
case0:
isSuccess=true;
break;
case1:
break;
default:
break;
}
}catch(InterruptedExceptione){
e.printStackTrace();
}
returnisSuccess;
}
}

如果要使用，还需以下步骤：

1、在AndroidManifest.xml文件里添加如下权限：

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

2、进行系统签名。命令如下：

java -jar signapk.jar platform.x509.pem platform.pk8 XXX.apk Signed_XXX.apk

备注：一般可在源码的目录\out\host\linux-x86\framework\下找到signapk.jar，在\build\target\product\security下找到签名文件platform.x509.pem和platform.pk8。

好了，现在大功告成！！！
