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

android9.0,默认apk权限添加方法

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

--- a/frameworks/base/services/core/java/com/android/server/pm/permission/DefaultPermissionGrantPolicy.java +++ b/frameworks/base/services/core/java/com/android/server/pm/permission/DefaultPermissionGrantPolicy.java @@ -94,7 +94,7 @@ import java.util.Set; */ public final class DefaultPermissionGrantPolicy { private static final String TAG = "DefaultPermGrantPolicy"; // must be <= 23 chars - private static final boolean DEBUG = false; + private static final boolean DEBUG = true; private static final int DEFAULT_FLAGS = PackageManager.MATCH_DIRECT_BOOT_AWARE | PackageManager.MATCH_DIRECT_BOOT_UNAWARE @@ -216,6 +216,7 @@ public final class DefaultPermissionGrantPolicy { } } }; + Slog.e(TAG,"vsoonbsp helloworld\n"); mPermissionGrantedCallback = callback; mPermissionManager = permissionManager; mServiceInternal = LocalServices.getService(PackageManagerInternal.class); @@ -263,8 +264,55 @@ public final class DefaultPermissionGrantPolicy { } } + //声明要赋予apk包名 + private static final String PCK_NAME_MICROSOFT = "com.microsoft.translator"; + private static final String PCK_NAME_TTS = "com.google.android.tts"; + private static final String PCK_NAME_SEARCH = "com.google.android.googlequicksearchbox"; + + private void grantPermissionsToCustomApp(int userId){ + try{ + PackageParser.Package customPackage = getSystemPackage(PCK_NAME_MICROSOFT); + if ((customPackage != null) && doesPackageSupportRuntimePermissions(customPackage)) { + grantRuntimePermissions(customPackage, LOCATION_PERMISSIONS, userId); + grantRuntimePermissions(customPackage, STORAGE_PERMISSIONS, userId); + grantRuntimePermissions(customPackage, MICROPHONE_PERMISSIONS, userId); + } + + customPackage = getSystemPackage(PCK_NAME_MICROSOFT); + if ((customPackage != null) && doesPackageSupportRuntimePermissions(customPackage)) { + grantRuntimePermissions(customPackage, LOCATION_PERMISSIONS, userId); + grantRuntimePermissions(customPackage, STORAGE_PERMISSIONS, userId); + grantRuntimePermissions(customPackage, MICROPHONE_PERMISSIONS, userId); + } + + customPackage = getSystemPackage(PCK_NAME_SEARCH); + if ((customPackage != null) && doesPackageSupportRuntimePermissions(customPackage)) { + grantRuntimePermissions(customPackage, LOCATION_PERMISSIONS, userId); + grantRuntimePermissions(customPackage, STORAGE_PERMISSIONS, userId); + grantRuntimePermissions(customPackage, MICROPHONE_PERMISSIONS, userId); + } + + + }catch(Exception e) { + e.printStackTrace(); + } + } + public void grantDefaultPermissions(int userId) { grantPermissionsToSysComponentsAndPrivApps(userId); + grantPermissionsToCustomApp(userId); 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
