本人开发更新新版本时候发现阿里上传compileSdkVersion要大于26,也就是安卓8.0才可以上传应用apk。于是将compileSdkVersion原来的25给成了26。但是测试过程中发现8.0以上的手机无法自动更新，下拉通知中心栏也没有进度条。广播也不能回调进度条。于是经过排查发现8.0意思的手机需要动态添加权限。
广播
8.0以下需要在AndroidManifest文件中进行静态的注册。8.0手机是接收不到的，需要动态注册。也就是说，不能在AndroidManifest文件对有些广播进行静态注册。
8.0以下的发送广播（需要在AndroidManifes添加以下代码）
<receiver
android:name=".updateAppUtils.util.UpdateAppReceiver"
android:enabled="true"
android:exported="false">
<intent-filter>
<action android:name="teprinciple.update"/>
</intent-filter>
</receiver>Intent intent = new Intent("teprinciple.update");
intent.putExtra("progress", progress);
intent.putExtra("title", serverVersionName);
context.sendBroadcast(intent);8.0发送的广播
Intent intent = new Intent("teprinciple.update");
ComponentName componentName = new ComponentName("", "");//参数1-包名 参数2-广播接收者所在的路径名
intent.putExtra("progress", progress);
intent.putExtra("title", serverVersionName);
intent.setComponent(componentName);
context.sendBroadcast(intent);广播发送完整代码
<receiver
android:name=".updateAppUtils.util.UpdateAppReceiver"
android:enabled="true"
android:exported="false">
<intent-filter>
<action android:name="teprinciple.update"/>
</intent-filter>
</receiver> private static void send(Context context, int progress, String serverVersionName) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
Intent intent = new Intent("teprinciple.update");
ComponentName componentName = new ComponentName("", "");//参数1-包名 参数2-广播接收者所在的路径名
intent.putExtra("progress", progress);
intent.putExtra("title", serverVersionName);
intent.setComponent(componentName);
context.sendBroadcast(intent);
} else {
Intent intent = new Intent("teprinciple.update");
intent.putExtra("progress", progress);
intent.putExtra("title", serverVersionName);
context.sendBroadcast(intent);
}
}获取是否有安装未知来源应用的权限
boolean haveInstallPermission = context.getPackageManager().canRequestPackageInstalls();广播接收,apk自动安装权限，下拉通知栏完整代码
