ContentProvider模块 [英] Module with ContentProvider

问题描述

我正在使用此库，问题始于:

I'm ussing this library, the problem starts with:

纸盘基于ContentProvider. ContentProvider需要一个唯一的 权威.当您对多个应用程序使用相同的权限时，您将 由于与的权限冲突而无法安装该应用 错误消息:

Tray is based on a ContentProvider. A ContentProvider needs a unique authority. When you use the same authority for multiple apps you will be unable to install the app due to a authority conflict with the error message:

失败[INSTALL_FAILED_CONFLICTING_PROVIDER]

Failure [INSTALL_FAILED_CONFLICTING_PROVIDER]

因为我之前没有读过这篇文章，所以我使用该库修复了多线程SharedPreference的问题，因此该项目必须放入一个模块中才能在多个项目中使用.

because i didn't read this before, i used this library to fix problems with multi thread SharedPreference, this project had to become in a module to use in multiple projects.

在使用此模块安装每个应用程序时，抛出失败[INSTALL_FAILED_CONFLICTING_PROVIDER] 异常.

At the moment of installing every App with this Module, throws the Failure [INSTALL_FAILED_CONFLICTING_PROVIDER] exception.

因为权限已在第一个安装的应用中使用.

Because authority is already used in the first installed app.

• 如何跳过已安装的模块的安装? (安装了该应用程序的其余部分，因此错误会消失)

• How can i skip installation of Module that is already installed? (Installing the rest of the app, so error will disapear)

否则，我该如何构建项目?才能安装使用带有ContentProvider库的模块构建的多个应用.

else, How can i structure the projects? to be able to install multiple apps built with the Module that have the ContentProvider Library.

Fixed

For those that need something similar these are the steps to follow:

第1步.我在"主项目"中配置了纸盘库"，其余的应用程序都需要" (托管数据库首选项的应用)

Step 1. I configured Tray Library in a Main Project "required for the rest of apps" (the app that hosts database preferences)

步骤2.我从存储库中提取了与Tray ContentProvider连接所需的类，

Step 2. I extracted from repository the required classes to connect with the Tray ContentProvider, which are:

• AbstractTrayPreference.java
• ContentProviderStorage.java
• ItemNotFoundException.java
• Migration.java
• OnTrayPreferenceChangeListener.java
• PreferenceAccessor.java
• Preferences.java
• PreferenceStorage.java
• SqliteHelper.java
• TrayContract.java
• TrayDBHelper.java
• TrayException.java
• TrayItem.java
• TrayPreferences.java
• TrayProviderHelper.java
• TrayRuntimeException.java
• TrayStorage.java
• TrayUri.java
• WrongTypeException.java

• AbstractTrayPreference.java
• ContentProviderStorage.java
• ItemNotFoundException.java
• Migration.java
• OnTrayPreferenceChangeListener.java
• PreferenceAccessor.java
• Preferences.java
• PreferenceStorage.java
• SqliteHelper.java
• TrayContract.java
• TrayDBHelper.java
• TrayException.java
• TrayItem.java
• TrayPreferences.java
• TrayProviderHelper.java
• TrayRuntimeException.java
• TrayStorage.java
• TrayUri.java
• WrongTypeException.java

位于通用模块的新包装中.

in a new package for the common Module.

第3步.我通过常量变量对权限名称进行了硬编码:

Step 3. I hardcoded authority name via constant variable:

这必须与主项目配置相符:

// bild.gradle of Main Project
resValue "string", "tray__authority", "<your.app.package>.tray"


// TrayContract.java of Module
@NonNull
private static String getAuthority(@NonNull final Context context) {
    return TextUtils.isEmpty(sTestAuthority) ?
            AppConstant.TRAY_AUTHORITY: // <-- this one = <your.app.package>.tray
            sTestAuthority;
}

最后，我可以正常使用该类:

Finally I can use the class normally:

// etc
import <your.app.package>.tray.TrayPreferences;
// etc
public class AppPreferencesManager extends TrayPreferences {
// etc
}

它起作用了:)
