升级到android9.0，在Android 8.1.0   oppo A5 报以下错误：

2021-04-07 09:46:38.078 18428-20051/? W/PackageInstaller.PackageInstaller: Error staging apk from content URI

在排查了以下代码：

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

public void installApplication(File fileapk) {
		this.mApkFile=fileapk;
		//int targetSdkVersion = this.getApplicationInfo().targetSdkVersion;
		//8.0后需要判断权限,targetSdkVersion小于26无需开启权限
		if (Build.VERSION.SDK_INT >=AndroidBuild.VERSION_CODES.O) {
			boolean hasInstallPermission = isHasInstallPermissionWithO(this);
			if (!hasInstallPermission) {
				startInstallPermissionSettingActivity();
				return;
			}
		}
		installApp();
	}
	private void installApp() {
		Intent intent = new Intent(Intent.ACTION_VIEW);
		intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
		//intent.setDataAndType(FileProviderUtils.getFileForUri(this,mApkFile,intent), "application/vnd.android.package-archive");
		FileProviderUtils.setIntentDataAndType(NewBaseApplication.getAppContext(),intent, "application/vnd.android.package-archive", mApkFile, true);
		startActivity(intent);
		ActivityStackUtils.getInstance().finishAllActivity(this, true);//部分手机需要注释掉这行代码
		android.os.Process.killProcess(android.os.Process.myPid());
	}
	@RequiresApi(api = AndroidBuild.VERSION_CODES.O)
	private boolean isHasInstallPermissionWithO(Context context){
		if (context == null){
			return false;
		}
		return context.getPackageManager().canRequestPackageInstalls();
	}

FileProviderUtils.java

  public static Uri getFileForUri(Context context, File mHeaderFile) {
        if (Build.VERSION.SDK_INT >= AndroidBuild.VERSION_CODES.N) {
            Uri imageUri = FileProvider.getUriForFile(context, context.getPackageName() + ".fileprovider", mHeaderFile);//通过
            return imageUri;
        } else {
            return Uri.fromFile(mHeaderFile);
        }
    }
 
    public static void setIntentDataAndType(Context context,Intent intent,String type,File file,boolean writeAble) {
        if (Build.VERSION.SDK_INT >= AndroidBuild.VERSION_CODES.N) {
            Uri uri=getFileForUri(context, file);
            intent.setDataAndType(uri, type);
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            if (writeAble) {
                intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
            }
            grantPermissions(context,intent,uri,writeAble);
        } else {
            intent.setDataAndType(Uri.fromFile(file), type);
        }
    }
 
    public static void grantPermissions(Context context, Intent intent, Uri uri, boolean writeAble) {
        int flag = Intent.FLAG_GRANT_READ_URI_PERMISSION;
        if (writeAble) {
            flag |= Intent.FLAG_GRANT_WRITE_URI_PERMISSION;
        }
        intent.addFlags(flag);
        List<ResolveInfo> resInfoList = context.getPackageManager()
                .queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
        for (ResolveInfo resolveInfo : resInfoList) {
            String packageName = resolveInfo.activityInfo.packageName;
            context.grantUriPermission(packageName, uri, flag);
        }
    }

最后把 手机管家-->权限隐私-->关联启动管理  里的当前应用 权限打开，就不会报错了
