android9.0 默认apk权限添加方法

1.默认赋予全部权限:
安卓动态要求用户允许添加权限，直接将如下代码中的final boolean grantPermissions = (args.installFlags
& PackageManager.INSTALL_GRANT_RUNTIME_PERMISSIONS) != 0;改为final boolean grantPermissions=true便可。

文件路径:framework\base\services\core\java\com\android\server\pm\PackageManagerService.java

case POST_INSTALL: {
                    if (DEBUG_INSTALL) Log.v(TAG, "Handling post-install for " + msg.arg1);

                    PostInstallData data = mRunningInstalls.get(msg.arg1);
                    final boolean didRestore = (msg.arg2 != 0);
                    mRunningInstalls.delete(msg.arg1);

                    if (data != null) {
                        InstallArgs args = data.args;
                        PackageInstalledInfo parentRes = data.res;
                        
                        /*final boolean grantPermissions = (args.installFlags
                                & PackageManager.INSTALL_GRANT_RUNTIME_PERMISSIONS) != 0;
                        */
                        //直接将grantPermissions该为true便可
                        final boolean grantPermissions = true;
                        final boolean killApp = (args.installFlags
                                & PackageManager.INSTALL_DONT_KILL_APP) == 0;
                        final boolean virtualPreload = ((args.installFlags
                                & PackageManager.INSTALL_VIRTUAL_PRELOAD) != 0);
                        final String[] grantedPermissions = args.installGrantPermissions;

                        // Handle the parent package
                        handlePackagePostInstall(parentRes, grantPermissions, killApp,
                                virtualPreload, grantedPermissions, didRestore,
                                args.installerPackageName, args.observer);

                        // Handle the child packages
                        final int childCount = (parentRes.addedChildPackages != null)
                                ? parentRes.addedChildPackages.size() : 0;
                        for (int i = 0; i < childCount; i++) {
                            PackageInstalledInfo childRes = parentRes.addedChildPackages.valueAt(i);
                            handlePackagePostInstall(childRes, grantPermissions, killApp,
                                    virtualPreload, grantedPermissions, false /*didRestore*/,
                                    args.installerPackageName, args.observer);
                        }

                        // Log tracing if needed
                        if (args.traceMethod != null) {
                            Trace.asyncTraceEnd(TRACE_TAG_PACKAGE_MANAGER, args.traceMethod,
                                    args.traceCookie);
                        }
                    } else {
                        Slog.e(TAG, "Bogus post-install token " + msg.arg1);
                    }

                    Trace.asyncTraceEnd(TRACE_TAG_PACKAGE_MANAGER, "postInstall", msg.arg1);
                } break;

2.根据包名赋予权限：

         grantDefaultSystemHandlerPermissions(userId);
         grantDefaultPermissionExceptions(userId);
     }

3.通过default-permissions-google.xml的方式
该文件编译的时候要编译到/system/etc/default-permissions/default-permissions-google.xml中。
可以使用Android.mk的PRODUCT_COPY_FILES方式拷贝。
关于default-permissions-google.xml相关的可以参考谷歌https://source.android.google.cn/devices/tech/config/perms-whitelist
