一、获取APK图标
public static Drawable getApkIcon(Context context, String apkPath) { PackageManager pm = context.getPackageManager(); PackageInfo info = pm.getPackageArchiveInfo(apkPath, PackageManager.GET_ACTIVITIES); if (info != null) { ApplicationInfo appInfo = info.applicationInfo; appInfo.sourceDir = apkPath; appInfo.publicSourceDir = apkPath; try { return appInfo.loadIcon(pm); } catch (OutOfMemoryError e) { Log.e("ApkIconLoader", e.toString()); } } return null; }下面代码段中PackageManager、PackageInfo、ApplicationInfo均同上面一致。 二、获取APK名称
String label = appInfo.loadLabel(mPackManager).toString();三、获取APK包名
String packageName = appInfo.packageName;四、获取APK版本号
String version = info.versionName==null?"0":info.versionName
五、推断APK是否安装
private boolean isApkInstalled(String packagename) { PackageManager localPackageManager = getPackageManager(); try { PackageInfo localPackageInfo = localPackageManager.getPackageInfo(packagename, PackageManager.GET_UNINSTALLED_PACKAGES); return true; } catch (PackageManager.NameNotFoundException localNameNotFoundException) { return false; } }六、安装APK
private void installAPK(String apkPath) { Intent intent = new Intent(); intent.setAction(Intent.ACTION_VIEW); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.setDataAndType(Uri.parse("file://" + apkPath),"application/vnd.android.package-archive"); mContext.startActivity(intent); }七、打开APK
private void openAPK(String packagename) { PackageManager packageManager = mContext.getPackageManager(); Intent intent=new Intent(); intent =packageManager.getLaunchIntentForPackage(packagename); mContext.startActivity(intent); }更多相关文章
