Android 一键唤醒应用

最近收到客户需求，需要设备实现一键唤醒应用功能，本次以录音机为例，一键唤醒应用功能具体修改参照如下：

/frameworks/base/services/core/java/com/android/server/policy/PhoneWindowManager.java

    public int interceptKeyBeforeQueueing(KeyEvent event, int policyFlags) {
    ...
    // Handle special keys.
    switch (keyCode) {
+            case KeyEvent.KEYCODE: {//uKEYCODE
+
+                String uPackageName = "com.android.soundrecorder";
+                String uClassName = "com.android.soundrecorder.SoundRecorder";
+
+                KeyguardManager mKeyguardManager = (KeyguardManager)mContext.getSystemService(Context.KEYGUARD_SERVICE);
+                boolean flag = mKeyguardManager.inKeyguardRestrictedInputMode();
+                   if(down){
+                            if(uPackageName != null && uClassName != null && !flag){
+                                Intent intent = new Intent();
+                                intent.setClassName(uPackageName,uClassName);
+                                if("com.android.soundrecorder".equals(uPackageName))
+                                mContext.startActivity(intent);
+                            }
+                    }
+                break;
+            }

重新编译验证，修改生效，设备已实现一键唤醒应用功能
