Question

我在按钮上有一个ussd代码。我在清单中添加了CALL_PHONE权限。我使用的是sdk版本（23）。此代码无法正常运行。

基本上我应该做什么？谢谢。

我有以下错误：

Answer 1

在Android Version > 23中，您必须在运行时询问权限。您没有在运行时询问用户CALL_PHONE和App崩溃。

这样的事情：

Learn more about asking permission at run time.

Answer 2

从SDK版本23及更高版本开始，您必须向用户请求运行时权限。必须从API级别23及更高级别提出要求。

您可以使用此代码，如果布尔值为true，则允许您调用。

在此行之前

if (requestCallPhonePermission(this)) {
ActivityMain.this.startActivityForResult(new Intent("android.intent.action.CALL", Uri.parse("tel:" + ussd)),1);
}  


@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
public static boolean requestCallPhonePermission(final Context context) {
    if (Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
        String callPhonePermission = Manifest.permission.CALL_PHONE;
        int hasPermission = ContextCompat.checkSelfPermission(context, callPhonePermission);
        final String[] permissions = new String[]{callPhonePermission};
        if (hasPermission != PackageManager.PERMISSION_GRANTED) {
                ActivityCompat.requestPermissions((Activity) context, permissions, PERMISSION_REQUEST_CALL_PHONE);
            return false;
        } else {
            return true;
        }
    }
    return true;
}

和同样的活动也可以获得许可。

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    switch (requestCode) {
        case PERMISSION_REQUEST_CALL_PHONE:
            if (grantResults.length <= 0 || grantResults[0] != PackageManager.PERMISSION_GRANTED) {
                Snackbar snackbar = Snackbar.make(CoordResident, R.string.permission_goto_setting, Snackbar.LENGTH_LONG);
                snackbar.setAction("Settings", new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        // open settings to enable permisions 
                    }
                });
                snackbar.show();
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}
