android快捷方式,访问启动器db

final String AUTHORITY = "com.android.launcher2.settings";  
final Uri CONTENT_URI = Uri.parse("content://" + 
                        AUTHORITY + "/favorites?notify=true");

Cursor c = contentResolver.query(uri,columns,null,null);

<uses-permission

Failed to find provider info for com.android.launcher2.settings

启动器是手机制造商责任下的应用程序.
然后,管理局并不总是“com.android.launcher2.settings”.
手机制造商可能会重写自己的手机.
它可以是“com.android.twlauncher”或其他任何东西,具体取决于Java包.

您需要通过搜索声明读/写权限“com.android.launcher.permission.READ_SETTINGS”或“com.android.launcher.permission.WRITE_SETTINGS”的提供程序来检索正确的权限.

这是一个示例代码：

static 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;
}

通常,保留ContentProvider和DB结构,您可以使用相同的查询.
