android6.0 安装自动确认 / 自动安装 / 静默安装

路径：

packages\apps\PackageInstaller\src\com\android\packageinstaller\PackageInstallerActivity.java

函数中：

private void startInstallConfirm()

模拟点确认：

        if (mScrollView == null) {
            // There is nothing to scroll view, so the ok button is immediately
            // set to install.
            mOk.setText(R.string.install);
            mOkCanInstall = true;
			mOk.performClick();
        } else {
            mScrollView.setFullScrollAction(new Runnable() {
                @Override
                public void run() {
                    mOk.setText(R.string.install);
                    mOkCanInstall = true;
					mOk.performClick();
                }
            });
        }

路径：

packages\apps\PackageInstaller\src\com\android\packageinstaller\InstallAppProgress.java

位置：

private Handler mHandler = new Handler() {
        public void handleMessage(Message msg) {
            switch (msg.what) {
                case INSTALL_COMPLETE:

加上：

mLaunchButton.performClick();

附近部分代码：

if (msg.arg1 == PackageManager.INSTALL_SUCCEEDED) {
                        mLaunchButton.setVisibility(View.VISIBLE);
                        centerTextDrawable.setLevel(0);
                        centerTextLabel = R.string.install_done;
                        // Enable or disable launch button
                        mLaunchIntent = getPackageManager().getLaunchIntentForPackage(
                                mAppInfo.packageName);
                        boolean enabled = false;
                        if(mLaunchIntent != null) {
                            List list = getPackageManager().
                                    queryIntentActivities(mLaunchIntent, 0);
                            if (list != null && list.size() > 0) {
                                enabled = true;
                            }
                        }
                        if (enabled) {
                            mLaunchButton.setOnClickListener(InstallAppProgress.this);
                        } else {
                            mLaunchButton.setEnabled(false);
                        }
                        mLaunchButton.performClick();
                    } else if (msg.arg1 == PackageManager.INSTALL_FAILED_INSUFFICIENT_STORAGE){
                        showDialogInner(DLG_OUT_OF_SPACE);
                        return;
                    }
