一、获取安装包信息
复制代码 代码如下:/**
* 获取apk包的信息：版本号，名称，图标等
* @param absPath apk包的绝对路径
* @param context
*/
public void apkInfo(String absPath,Context context) {
PackageManager pm = context.getPackageManager();
PackageInfo pkgInfo = pm.getPackageArchiveInfo(absPath,PackageManager.GET_ACTIVITIES);
if (pkgInfo != null) {
ApplicationInfo appInfo = pkgInfo.applicationInfo;
/* 必须加这两句，不然下面icon获取是default icon而不是应用包的icon */
appInfo.sourceDir = absPath;
appInfo.publicSourceDir = absPath;
String appName = pm.getApplicationLabel(appInfo).toString();// 得到应用名
String packageName = appInfo.packageName; // 得到包名
String version = pkgInfo.versionName; // 得到版本信息
/* icon1和icon2其实是一样的 */
Drawable icon1 = pm.getApplicationIcon(appInfo);// 得到图标信息
Drawable icon2 = appInfo.loadIcon(pm);
String pkgInfoStr = String.format("PackageName:%s, Vesion: %s, AppName: %s", packageName, version, appName);
Log.i(TAG, String.format("PkgInfo: %s", pkgInfoStr));
}
}
二、在APK安装的时候，我们可以获取安装包、版本、包名等信息。
复制代码 代码如下:
public class TestActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String archiveFilePath="sdcard/jb51.net.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(TestActivity.this, , Toast.LENGTH_LONG).show();
Drawable icon = pm.getApplicationIcon(appInfo);//得到图标信息
TextView tv = (TextView)findViewById(R.id.tv);
tv.setText("appName:"+appName+"---packageName:"+packageName);
//显示图标
ImageView tu=(ImageView)findViewById(R.id.imageView1);
tu.setBackgroundDrawable(icon);
}
}
}
}
}
