兼容7.0下载安装及打开相机相册适配问题记录

一、兼容7.0安装新版本及安装之后打开app

//安装工具类
public class InstallUtil {

/**
* 通过非Root模式安装
*
* @param context
* @param apkPath
*/
public static void install(Context context, String apkPath) {
//提升读写权限,否则可能出现解析异常
setPermission(apkPath);
installNormal(context, apkPath);
}

/**
* 提升读写权限
* @param filePath 文件路径
* @return
* @throws IOException
*/
public static void setPermission(String filePath)  {
String command = "chmod " + "777" + " " + filePath;
Runtime runtime = Runtime.getRuntime();
try {
runtime.exec(command);
} catch (IOException e) {
e.printStackTrace();
}
}

//普通安装
private static void installNormal(Context context, String apkPath) {
Intent intent = new Intent(Intent.ACTION_VIEW);

//加上这句话解决安装之后可以显示开打app的页面配合Process.killProcess(Process.myPid());使用
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

//版本在7.0以上是不能直接通过uri访问的
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
File file = (new File(apkPath));
//添加这一句表示对目标应用临时授权该Uri所代表的文件
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
// 由于没有在Activity环境下启动Activity,设置下面的标签
//参数1 上下文, 参数2 Provider主机地址 和配置文件中保持一致   参数3  共享的文件
Uri apkUri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID+".fileprovider", file);
intent.setDataAndType(apkUri, "application/vnd.android.package-archive");
} else {
intent.setDataAndType(Uri.fromFile(new File(apkPath)),
"application/vnd.android.package-archive");
}
context.startActivity(intent);
//加上这句话解决安装之后可以显示开打app的页面配合FLAG_ACTIVITY_NEW_TASK使用
Process.killProcess(Process.myPid());
}
}

在AndroidManifest.xml中配置

<!-- 解决7.0以上文件权限问题 -->
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_path" />
</provider>

在res新建xml文件夹，新建file_path.xml文件

<?xml version="1.0" encoding="utf-8"?>
<paths>
<!--        xml文件是唯一设置分享的目录 ，不能用代码设置

1.<files-path>        getFilesDir()  /data/data//files目录
2.<cache-path>        getCacheDir()  /data/data//cache目录

3.<external-path>     Environment.getExternalStorageDirectory()

SDCard/Android/data/你的应用的包名/files/ 目录
4.<external-files-path>     Context#getExternalFilesDir(String) Context.getExternalFilesDir(null).
5.<external-cache-path>      Context.getExternalCacheDir().
-->

<!--    path :代表设置的目录下一级目录 eg：<external-path path="images/"
整个目录为Environment.getExternalStorageDirectory()+"/images/"
name: 代表定义在Content中的字段 eg：name = "myimages" ，并且请求的内容的文件名为default_image.jpg
则 返回一个URI   content://com.example.myapp.fileprovider/myimages/default_image.jpg
-->

<!--下载apk-->
<external-path
name="sdcard_files"
path="" />
<!--相机相册裁剪-->
<external-files-path
name="camera_has_sdcard"
path="file/" />
<files-path
name="camera_no_sdcard"
path="" />
<root-path
name="external_files"
path="/storage" />
</paths>
