Android 4.0.4系统下实现apk的静默安装和启动

[日期：2013-02-15] 来源：Linux社区 作者：imyfriend [字体：大 中 小]

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：

import java.io.DataOutputStream;

import java.io.File;

import java.io.IOException;

import java.io.OutputStream;

import java.util.ArrayList;

import java.util.List;

import android.content.Context;

import android.content.Intent;

import android.content.pm.ActivityInfo;

import android.content.pm.PackageInfo;

import android.content.pm.PackageManager;

import android.content.pm.ResolveInfo;

public class InstallApkUtils {

public static void installAndStartApk(final Context context, final String apkPath) {

if ((apkPath==null) || (context==null)) {

return;

}

File file = new File(apkPath);

if (file.exists() == false) {

return;

}

new Thread() {

public void run() {

String packageName = getUninstallApkPackageName(context, apkPath);

if (silentInstall(apkPath)) {

List<ResolveInfo> matches = findActivitiesForPackage(context, packageName);

if ((matches!=null) && (matches.size()>0)) {

ResolveInfo resolveInfo = matches.get(0);

ActivityInfo activityInfo = resolveInfo.activityInfo;

startApk(activityInfo.packageName, activityInfo.name);

}

}

};

}.start();

}

public static String getUninstallApkPackageName(Context context, String apkPath) {

String packageName = null;

if (apkPath == null) {

return packageName;

}

PackageManager pm = context.getPackageManager();

PackageInfo info = pm.getPackageArchiveInfo(apkPath,

PackageManager.GET_ACTIVITIES);

if (info == null) {

return packageName;

}

packageName = info.packageName;

return packageName;

}

public static List<ResolveInfo> findActivitiesForPackage(Context context, String packageName) {

final PackageManager pm = context.getPackageManager();

final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);

mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);

mainIntent.setPackage(packageName);

final List<ResolveInfo> apps = pm.queryIntentActivities(mainIntent, 0);

return apps != null ? apps : new ArrayList<ResolveInfo>();

}

public static boolean silentInstall(String apkPath) {

String cmd1 = "chmod 777 " + apkPath + " \n";

String cmd2 = "LD_LIBRARY_PATH=/vendor/lib:/system/lib pm install -r " + apkPath + " \n";

return execWithSID(cmd1, cmd2);

}

private static boolean execWithSID(String... args) {

boolean isSuccess = false;

Process process = null;

OutputStream out = null;

try {

process = Runtime.getRuntime().exec("su");

out = process.getOutputStream();

DataOutputStream dataOutputStream = new DataOutputStream(out);

for (String tmp : args) {

dataOutputStream.writeBytes(tmp);

}

dataOutputStream.flush(); // 提交命令

dataOutputStream.close(); // 关闭流操作

out.close();

isSuccess = waitForProcess(process);

} catch (IOException e) {

e.printStackTrace();

}

return isSuccess;

}

public static boolean startApk(String packageName, String activityName) {

boolean isSuccess = false;

String cmd = "am start -n " + packageName + "/" + activityName + " \n";

try {

Process process = Runtime.getRuntime().exec(cmd);

isSuccess = waitForProcess(process);

} catch (IOException e) {

NLog.i(TAG, e.getMessage());

e.printStackTrace();

}

return isSuccess;

}

private static boolean waitForProcess(Process p) {

boolean isSuccess = false;

int returnCode;

try {

returnCode = p.waitFor();

switch (returnCode) {

case 0:

isSuccess = true;

break;

case 1:

break;

default:

break;

}

} catch (InterruptedException e) {

e.printStackTrace();

}

return isSuccess;

}

}

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

好了，现在大功告成！！！
