我通过PackageManager检查功能
final PackageManager packageManager = context.getPackageManager();
final Intent intent = new Intent(Intent.ACTION_CALL);
List<ResolveInfo> list =
packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
return list.size() > 0;
但无论如何结果都是假的。申请是在平板电脑和手机上,但结果是一样的。哪里错了?
答案 0 :(得分:3)
你应该试试这个:
PackageManager pm = this.getPackageManager();
if (pm.hasSystemFeature(PackageManager.FEATURE_TELEPHONY)) {
System.out.println("horray");
} else {
System.out.println("nope");
}
编辑:要检查Skype是否已安装在设备中?
通过以下方法传递Skype
URI。
private boolean appInstalledOrNot(String uri) {
PackageManager pm = getPackageManager();
boolean app_installed = false;
try {
pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
app_installed = true;
}
catch (PackageManager.NameNotFoundException e) {
app_installed = false;
}
return app_installed ;
}
