本文介绍了一个Android应用程序，该程序能够获取并展示安装在设备上的所有应用及其对应的权限信息。通过遍历已安装的应用程序包，利用Android系统的包管理器服务获取应用详情及权限列表，并将这些信息展示给用户。

package gongzibai.co.cc;

import java.util.List;

import android.app.Activity;
import android.app.Application;
import android.content.pm.ApplicationInfo;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.content.pm.PermissionInfo;
import android.os.Bundle;
import android.widget.TextView;

public class Package1Activity extends
Activity {
TextView mTextView;

/** Called when the activity is first created. */
@Override
public void onCreate(
Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mTextView = (TextView) findViewById(R.id.textView1);
PackageManager packageManager = getPackageManager();

List<PackageInfo> list = packageManager
.getInstalledPackages(PackageManager.GET_PERMISSIONS);
StringBuilder stringBuilder = new StringBuilder();

for (PackageInfo packageInfo : list) {

stringBuilder
.append("package name:"
+ packageInfo.packageName
+ "\n");
ApplicationInfo applicationInfo = packageInfo.applicationInfo;
stringBuilder
.append("应用名称:"
+ applicationInfo
.loadLabel(packageManager)
+ "\n");

if (packageInfo.permissions != null) {

for (PermissionInfo p : packageInfo.permissions) {

stringBuilder
.append("权限包括:"
+ p.name
+ "\n");
}

}
stringBuilder.append("\n");
}

mTextView.setText(stringBuilder
.toString());

}
}
