1.Android 6.0 以后三方Launcher不响应Home键
关键代码片段
./services/core/java/com/android/server/policy/PhoneWindowManager.java
7970 boolean goHome() {
7971 if (!isUserSetupComplete()) {
7972 Slog.i(TAG, "Not going home because user setup is in progress.");
7973 return false;
7974 }
... ... ... ...
./services/core/java/com/android/server/policy/PhoneWindowManager.java
1848 boolean isUserSetupComplete() {
1849 boolean isSetupComplete = Settings.Secure.getIntForUser(mContext.getContentResolver(),
1850 Settings.Secure.USER_SETUP_COMPLETE, 0, UserHandle.USER_CURRENT) != 0;
1851 if (mHasFeatureLeanback) {
1852 isSetupComplete &= isTvUserSetupComplete();
1853 }
1854 return isSetupComplete;
1855 }
因此只需要更改数据库配置即可
settings put secure user_setup_complete 1
settings put secure tv_user_setup_complete 1
或代码执行
TvProvision/src/com/android/tv/provision/DefaultActivity.java
32 public class DefaultActivity extends Activity {
33
34 @Override
35 protected void onCreate(Bundle icicle) {
36 super.onCreate(icicle);
37
38 // Add a persistent setting to allow other apps to know the device has been provisioned.
39 if (!isRestrictedUser()) {
40 Settings.Global.putInt(getContentResolver(), Settings.Global.DEVICE_PROVISIONED, 1);
41 }
42 Settings.Secure.putInt(getContentResolver(), Settings.Secure.USER_SETUP_COMPLETE, 1);
43 Settings.Secure.putInt(getContentResolver(), Settings.Secure.TV_USER_SETUP_COMPLETE, 1);
2.Android Settings dump
dumpsys settings --proto
or
settings list system/secure/global
3.Android 修改音量键风格

4.系统应用预授权
修改etc/default-permissions 下配置xml即可。示例可参考
device/google/crosshatch/default-permissions.xml
./services/core/java/com/android/server/pm/permission/DefaultPermissionGrantPolicy.java
1309 private void grantDefaultPermissionExceptions(int userId) {
1310 mHandler.removeMessages(MSG_READ_DEFAULT_PERMISSION_EXCEPTIONS);
1311
1312 synchronized (mLock) {
1313 // mGrantExceptions is null only before the first read and then
1314 // it serves as a cache of the default grants that should be
1315 // performed for every user. If there is an entry then the app
1316 // is on the system image and supports runtime permissions.
1317 if (mGrantExceptions == null) {
1318 mGrantExceptions = readDefaultPermissionExceptionsLocked();
1319 }
1320 }
1321
1322 Set<String> permissions = null;
1323 final int exceptionCount = mGrantExceptions.size();
1324 for (int i = 0; i < exceptionCount; i++) {
1325 String packageName = mGrantExceptions.keyAt(i);
1326 PackageParser.Package pkg = getSystemPackage(packageName);
1327 List<DefaultPermissionGrant> permissionGrants = mGrantExceptions.valueAt(i);
1328 final int permissionGrantCount = permissionGrants.size();
1329 for (int j = 0; j < permissionGrantCount; j++) {
1330 DefaultPermissionGrant permissionGrant = permissionGrants.get(j);
1331 if (permissions == null) {
1332 permissions = new ArraySet<>();
1333 } else {
1334 permissions.clear();
1335 }
1336 permissions.add(permissionGrant.name);
1337 grantRuntimePermissions(pkg, permissions,
1338 permissionGrant.fixed, userId);
