How To Unset My Sms App As Default App In Android

I want to unset whether my SMS app as default app in android. I am following this tutorial: http://android-developers.blogspot.com/2013/10/getting-your-sms-apps-ready-for-kitkat.ht

Solution 1:

To un-select your app as the default SMS app, you can let the user choose another eligible app to act as the default in place of yours, and fire the ACTION_CHANGE_DEFAULTIntent with that package name.

To simplify the process, I wrote the selectDefaultSmsPackage() method that will find all apps that accept the "android.provider.Telephony.SMS_DELIVER" broadcast (excluding the current package), and prompt the user with a list to choose from. This is a rather naive filtering criterion, but the worst that should happen is that a selected app just won't be successfully set as the default.

After selecting the desired app from the list, the usual yes/no verification dialog will appear. When the Activity receives the result, the selected app's package name is compared to that currently set as default to determine success. As some users have reported that the result code is not reliable in this case, checking the current default is about the only way to guarantee a correct success result.

We will be using a custom Dialog to list the display names and icons of eligible apps. The Activity creating the AppsDialog must implement its OnAppSelectedListener interface.

publicclassMainActivityextendsActivityimplementsAppsDialog.OnAppSelectedListener {
    ...

    privatestaticfinalintDEF_SMS_REQ=0;
    private AppInfo selectedApp;

    privatevoidselectDefaultSmsPackage() {
        final List<ResolveInfo> receivers = getPackageManager().
            queryBroadcastReceivers(newIntent(Sms.Intents.SMS_DELIVER_ACTION), 0);

        final ArrayList<AppInfo> apps = newArrayList<>();
        for (ResolveInfo info : receivers) {
            finalStringpackageName= info.activityInfo.packageName;

            if (!packageName.equals(getPackageName())) {
                finalStringappName= getPackageManager()
                    .getApplicationLabel(info.activityInfo.applicationInfo)
                    .toString();
                finalDrawableicon= getPackageManager()
                    .getApplicationIcon(info.activityInfo.applicationInfo);

                apps.add(newAppInfo(packageName, appName, icon));
            }
        }

        Collections.sort(apps, newComparator<AppInfo>() {
                @Overridepublicintcompare(AppInfo app1, AppInfo app2) {
                    return app1.appName.compareTo(app2.appName);
                }
            }
        );

        newAppsDialog(this, apps).show();
    }

    @OverridepublicvoidonAppSelected(AppInfo selectedApp) {
        this.selectedApp = selectedApp;

        Intentintent=newIntent(Sms.Intents.ACTION_CHANGE_DEFAULT);
        intent.putExtra(Sms.Intents.EXTRA_PACKAGE_NAME, selectedApp.packageName);
        startActivityForResult(intent, DEF_SMS_REQ);
    }

    @OverrideprotectedvoidonActivityResult(int requestCode, int resultCode, Intent data) {
        switch (requestCode) {
            case DEF_SMS_REQ:
                StringcurrentDefault= Sms.getDefaultSmsPackage(this);
                booleanisDefault= selectedApp.packageName.equals(currentDefault);

                Stringmsg= selectedApp.appName + (isDefault ?
                    " successfully set as default" :
                    " not set as default");

                Toast.makeText(this, msg, Toast.LENGTH_SHORT).show();

                break;
            ...
        }
    }

We need the following POJO class to hold the relevant app information.

publicclassAppInfo {
    String appName;
    String packageName;
    Drawable icon;

    publicAppInfo(String packageName, String appName, Drawable icon) {
        this.packageName = packageName;
        this.appName = appName;
        this.icon = icon;
    }

    @OverridepublicStringtoString() {
        return appName;
    }
}

The AppsDialog class creates a simple ListView of the available defaults, and passes the selection back to the Activity through the interface.

publicclassAppsDialogextendsDialogimplementsOnItemClickListener {

    publicinterfaceOnAppSelectedListener {
        publicvoidonAppSelected(AppInfo selectedApp);
    }

    privatefinal Context context;
    privatefinal List<AppInfo> apps;

    publicAppsDialog(Context context, List<AppInfo> apps) {
        super(context);

        if (!(context instanceof OnAppSelectedListener)) {
            thrownewIllegalArgumentException(
                "Activity must implement OnAppSelectedListener interface");
        }

        this.context = context;
        this.apps = apps;
    }

    @OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setTitle("Select default SMS app");

        finalListViewlistView=newListView(context);
        listView.setAdapter(newAppsAdapter(context, apps));
        listView.setOnItemClickListener(this);
        setContentView(listView);
    }

    @OverridepublicvoidonItemClick(AdapterView<?> parent, View view, int position, long id) {
        ((OnAppSelectedListener) context).onAppSelected(apps.get(position));
        dismiss();
    }

    privateclassAppsAdapterextendsArrayAdapter<AppInfo> {
        publicAppsAdapter(Context context, List<AppInfo> list) {
            super(context, R.layout.list_item, R.id.text, list);
        }

        public View getView(int position, View convertView, ViewGroup parent) {
            finalAppInfoitem= getItem(position);

            Viewv=super.getView(position, convertView, parent); 
            ((ImageView) v.findViewById(R.id.icon)).setImageDrawable(item.icon);

            return v;
        }
    }
}

The ArrayAdapter uses the following item layout, list_item.

<LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="wrap_content"android:gravity="center_vertical"android:paddingTop="1dp"android:paddingBottom="1dp"android:paddingStart="8dp"android:paddingEnd="8dp"><ImageViewandroid:id="@+id/icon"android:layout_width="36dp"android:layout_height="36dp" /><TextViewandroid:id="@+id/text"android:layout_width="match_parent"android:layout_height="wrap_content"android:gravity="center_vertical"android:textAppearance="?android:attr/textAppearanceListItemSmall"android:paddingStart="?android:attr/listPreferredItemPaddingStart"android:paddingEnd="?android:attr/listPreferredItemPaddingEnd"android:minHeight="?android:attr/listPreferredItemHeightSmall"android:ellipsize="marquee" /></LinearLayout>
