Storing value into Intent without start a new Activity

Question

I have to retrieve the total number of permits required by the application, and store this value for use in a second Activity, but without letting it open with the intent. I wrote this code.

    try {
        PackageInfo packageInfo = getActivity().getPackageManager().getPackageInfo(value2, PackageManager.GET_PERMISSIONS);

        String[] requestedPermissions = packageInfo.requestedPermissions;
        if ( requestedPermissions != null ) {
            for ( i = 0; i < requestedPermissions.length; i++) {
                permissions.append(requestedPermissions[i]+"\n");
                int total = i++;
                Intent intent = new Intent();
                intent.putExtra("totalPermissions",total);

            }
        }
    }
    catch ( PackageManager.NameNotFoundException e ) {
        e.printStackTrace();
    }

In another PreferenceActivity

Bundle extras = getIntent().getExtras();
        if(extras!=null) {
        int tot = extras.getInt("totalPermissions");

permissionsPreference.setSummary(""+tot);

In the Summary of Prefence return 0. Why? Where is the error?

Answer 1

您在使用价值并从意图中获取价值时使用了不同的键，这就是为什么您获得零的原因。

Answer 2

The two intent are not the same one. You can make a public static int total; Modify its value in the first activity, and get its value in the second activity by FirstActivity.total
