Android打开应用市场

查看手机中所有的应用市场：

Intent intent = new Intent();
intent.setAction("android.intent.action.MAIN");
intent.addCategory("android.intent.category.APP_MARKET");
PackageManager pm = this.getPackageManager();
List<ResolveInfo> infos = pm.queryIntentActivities(intent, 0);
int size = infos.size();
for (int i = 0; i < size; i++) {
   ActivityInfo activityInfo = infos.get(i).activityInfo;
   String packageName = activityInfo.packageName;
   Log.i( TAG, "packageName : " + packageName);
}

 注：不一定能够显示全部市场。

 

根据市场包名和App包名打开指定应用市场并进入到App的详情界面：

Intent intent = new Intent(Intent.ACTION_VIEW);
Uri uri = Uri.parse("market://details?id=" + "com.tencent.mm");
intent.setData(uri);
intent.setPackage("com.tencent.android.qqdownloader");
startActivity(intent);
