开发板 Android7.1 适配 Android10.0---记录

1.启动服务的变更：
第一步：使用startForegroundService来启动service

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
     startForegroundService(new Intent(this, MyService.class));
  } else {
     startService(new Intent(this, MyService.class));
  }

第二步：在myService的onCreate中添加一下代码

NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
NotificationChannel mChannel = null;
       if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
           mChannel = new NotificationChannel("service_01", getString(R.string.app_name),NotificationManager.IMPORTANCE_LOW);
           notificationManager.createNotificationChannel(mChannel);
           Notification notification = new Notification.Builder(getApplicationContext(), "service_01").build();
           startForeground(1, notification);
       }

第三步：在manifest中添加权限

<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>

2.Android10的sd卡读写权限使用了沙盘模式。但也提供了一个兼容代码
在application中添加android:requestLegacyExternalStorage=“true”

<application
android:requestLegacyExternalStorage="true"
</application>

3.android 10 限制了使用http请求；可通过一下做兼容：
a.在res目录下创建xml目录,然后随便创建一个myNetwork.xml文件,里面内容如下:

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
   <base-config cleartextTrafficPermitted="true" />
</network-security-config>

b.然后在application中添加android:networkSecurityConfig="@xml/myNetwork"

<application
android:networkSecurityConfig="@xml/myNetwork"
</application>

4.智能安装步骤：
a.

 private void smartInstall(String apkPath) {
       if(Build.VERSION.SDK_INT >= 24) {//判读版本是否在7.0以上
           Uri apkUri = FileProvider.getUriForFile(getView().getContext(), "包名.fileprovider", new File(apkPath));//在AndroidManifest中的android:authorities值
           Intent install = new Intent(Intent.ACTION_VIEW);
           install.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
           install.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
           install.setDataAndType(apkUri, "application/vnd.android.package-archive");
           getView().getContext().startActivity(install);
       } else{
           Intent install = new Intent(Intent.ACTION_VIEW);
           install.setDataAndType(Uri.fromFile(new File(apkPath)), "application/vnd.android.package-archive");
           install.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
           getView().getContext().startActivity(install);
       }
   }

b. 在manifase中添加provider 标签，如下代码

<application
	 <provider
            android:authorities="包名.fileprovider"
            android:name="androidx.core.content.FileProvider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_paths" />
        </provider>
</application>

c.在res目录下创建xml目录,然后随便创建一个file_paths.xml文件,里面内容如下:

<paths>
 <external-path path="" name="ihelmet"/>
</paths>
