客户需求要求Google Play Store（Phonesky.apk）为可卸载，需要放到system/vendor/operator/app下面。这样在登录Play Store时会遇到以下错误，无法使用：这是因为非系统应用无法拥有android.permission.ACCESS_DOWNLOAD_MANAGER权限，而在DownloadProvider的insert函数中会调用checkInsertPermissions检查数据库操作权限，如下：
private void checkInsertPermissions(ContentValues values) {
if (getContext().checkCallingOrSelfPermission(Downloads.Impl.PERMISSION_ACCESS)
== PackageManager.PERMISSION_GRANTED) {
return;
}
getContext().enforceCallingOrSelfPermission(android.Manifest.permission.INTERNET,
"INTERNET permission is required to use the download manager");
// ensure the request fits within the bounds of a public API request
// first copy so we can remove values
values = new ContentValues(values);
// check columns whose values are restricted
enforceAllowedValues(values, Downloads.Impl.COLUMN_IS_PUBLIC_API, Boolean.TRUE);
……
}
解决方案：
【方法一】将Google Play Store放回系统应用区，不做可卸载处理。这样虽然简单，却没有实现客户需求。
【方法二】修改PackageManagerService源码，对Google Play Store做特殊处理，直接给予权限：
--- a/frameworks/base/services/java/com/android/server/pm/PackageManagerService.java
+++ b/frameworks/base/services/java/com/android/server/pm/PackageManagerService.java
@@ -5938,7 +5938,12 @@ public class PackageManagerService extends IPackageManager.Stub {
+ ")");
}
}
+ // TChip ZJ Add START:for Phoneshy Permission
+ if (pkg.packageName.equals("com.android.vending")){
+ allowed = true;
+ }
+ // TChip ZJ Add END
}
if ((changedPermission || replace) && !ps.permissionsFixed &&
!isSystemApp(ps) || isUpdatedSystemApp(ps)){
Android将Google Play Store放到可卸载区，登录时报SecurityException错误
