Android 判斷桌面快捷方式是否存在

1、在桌面增加Android應用快捷方式

public void createShortCut() {
// 創建快捷方式的Intent
Intent shortcutintent = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");
// 不允許重復創建
shortcutintent.putExtra("duplicate", false);
// 需要現實的名稱
shortcutintent.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.app_name));
// 快捷圖片
Parcelable icon = Intent.ShortcutIconResource.fromContext(getApplicationContext(), R.drawable.ic_launcher);
shortcutintent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, icon);
// 點擊快捷圖片，運行的程序主入口
shortcutintent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, new Intent(getApplicationContext(), SplashActivity.class));
// 發送廣播。OK
sendBroadcast(shortcutintent);
}

在AndroidManifest.xml中增加權限

<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />

2、判斷快捷方式是否已經存在

public boolean hasShortcut(Activity activity, String shortcutName) {
String url = "";
url = "content://" + getAuthorityFromPermission(activity, "com.android.launcher.permission.READ_SETTINGS") + "/favorites?notify=true";
ContentResolver resolver = activity.getContentResolver();
Cursor cursor = resolver.query(Uri.parse(url), new String[] { "title", "iconResource" }, "title=?", new String[] { getString(R.string.app_name).trim() }, null);
if (cursor != null && cursor.moveToFirst()) {
cursor.close();
return true;
}
return false;
}

在AndroidManifest.xml中增加權限

<uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />

因為不同的手機廠商可能對手機系統進行了修改使用原生的

“content://com.android.launcher.settings/favorites?notify=true"

或者

"content://com.android.launcher2.settings/favorites?notify=true"

並不能准確判斷 需要通過權限去獲取當前手機provider.authority

private String getAuthorityFromPermission(Context context, String permission) {
if (permission == null)
return null;
List<PackageInfo> packs = context.getPackageManager().getInstalledPackages(PackageManager.GET_PROVIDERS);
if (packs != null) {
for (PackageInfo pack : packs) {
ProviderInfo[] providers = pack.providers;
if (providers != null) {
for (ProviderInfo provider : providers) {
if (permission.equals(provider.readPermission))
return provider.authority;
if (permission.equals(provider.writePermission))
return provider.authority;
}
}
}
}
return null;
}
