在APK安装的时候，我们可以获取安装包、版本、包名等信息。
public class test4 extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String archiveFilePath="sdcard/download/yige_org.apk";//安装包路径
PackageManager pm = getPackageManager();
PackageInfo info = pm.getPackageArchiveInfo(archiveFilePath, PackageManager.GET_ACTIVITIES);
if(info != null){
ApplicationInfo appInfo = info.applicationInfo;
String appName = pm.getApplicationLabel(appInfo).toString();
String packageName = appInfo.packageName; //得到安装包名称
String version=info.versionName; //得到版本信息
Toast.makeText(test4.this, "packageName:"+packageName+";version:"+version, Toast.LENGTH_LONG).show();
Drawable icon = pm.getApplicationIcon(appInfo);//得到图标信息
TextView tv = (TextView)findViewById(R.id.tv); //显示图标
tv.setBackgroundDrawable(icon);
}
}
}
