Android shortcut creation failure bug [resolved]

Pay special attention to the following questions about the inability to create shortcuts:

In many cases, the meaning of this sentence is to prevent duplicate creation of shortcuts, but the problem I encountered today is that this sentence makes it impossible to create shortcuts on the desktop.

My approach is:

1. Use SharedPreferences to determine whether the application is started for the first time.

2. Use isInstallShortcut () to determine whether there is a shortcut

3. Create a shortcut (

private void createShortCut() {        SharedPreferences userini = getSharedPreferences(                getString(R.string.useriniXML), Activity.MODE_PRIVATE);        Log.e("H3c","sh.."+userini.getInt("seflshotcut", 0));        if (userini.getInt("seflshotcut", 0) == 0) {            m_tool.createShortCut(Main.this);            SharedPreferences.Editor sEdi = userini.edit();            sEdi.putInt("seflshotcut", 1);            sEdi.commit();        }    }

private boolean isInstallShortcut() {        boolean isInstallShortcut = false;        final ContentResolver cr = MarketApplication                .getMarketApplicationContext().getContentResolver();        String AUTHORITY = "com.android.launcher.settings";        Uri CONTENT_URI = Uri.parse("content://" + AUTHORITY                + "/favorites?notify=true");        Cursor c = cr.query(CONTENT_URI,                new String[] { "title", "iconResource" }, "title=?",                new String[] { "XXXX" }, null);        if (c != null && c.getCount() > 0) {            isInstallShortcut = true;        }        if (c != null) {            c.close();        }        if (isInstallShortcut) {            return isInstallShortcut;        }        AUTHORITY = "com.android.launcher2.settings";        CONTENT_URI = Uri.parse("content://" + AUTHORITY                + "/favorites?notify=true");        c = cr.query(CONTENT_URI, new String[] { "title", "iconResource" },                "title=?", new String[] { "XXXX" }, null);        if (c != null && c.getCount() > 0) {            isInstallShortcut = true;        }        return isInstallShortcut;    }

3.

/*** Create shortcuts **/public void createShortCut (Context contxt) {if (isInstallShortcut () {// if it has been created once, no return will be created ;} intent sIntent = new Intent (Intent. ACTION_MAIN); sIntent. addCategory (Intent. CATEGORY_LAUNCHER); // after adding action and category, the sIntent is automatically uninstalled when the program is uninstalled. setClass (contxt, Login. class); Intent installer = new Intent (); // installer. putExtra ("duplicate", false); installer. putExtra ("android. intent. extra. shortcut cut. INTENT ", sIntent); installer. putExtra ("android. intent. extra. shortcut cut. NAME "," XXXX "); installer. putExtra ("android. intent. extra. shortcut cut. ICON_RESOURCE ", Intent. using cuticonresource. fromContext (contxt, R. drawable. icon); installer. setAction ("com. android. launcher. action. INSTALL_SHORTCUT "); contxt. sendBroadcast (installer );}
