Android 静默安装apk

代码：

import java.io.File;
import android.app.Activity;
import android.os.Bundle;
import android.content.Intent;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.content.pm.PackageManager.NameNotFoundException;
import android.content.pm.IPackageInstallObserver;
import android.content.pm.IPackageDeleteObserver;
import android.content.res.Resources;
import android.graphics.drawable.Drawable;
import android.net.Uri;
import android.os.Environment;
import android.os.Handler;
import android.os.Message;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ProgressBar;
import android.widget.TextView;

public class InstallActivity extends Activity {
	/** Called when the activity is first created. */
	private Button btn1;
	private Button btn2;
	private final int INSTALL_COMPLETE = 1;
	private final int UNINSTALL_COMPLETE = 1;
	final static int SUCCEEDED = 1;
	final static int FAILED = 0;

	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

		btn1 = (Button) findViewById(R.id.btn1);
		btn2.setOnClickListener(listener1);
		btn2 = (Button) findViewById(R.id.btn2);
		btn2.setOnClickListener(listener2);
	}

	private OnClickListener listener1 = new OnClickListener() {
		public void onClick(View v) {
			String apkPath = Environment.getExternalStorageDirectory()
					+ "/baidu/" + "UC.apk";
			String packageName = "com.uc.browser";
			install(apkPath, packageName);
		}
	};
	private OnClickListener listener2 = new OnClickListener() {
		public void onClick(View v) {
			String packageName = "com.uc.browser";
			uninstall(packageName);
		}
	};

	// 安装
	public void install(String apkPath, String packageName) {
		Uri uri = Uri.fromFile(new File(apkPath));
		int installFlags = 0;
		PackageManager pm = getPackageManager();
		try {
			PackageInfo pi = pm.getPackageInfo(packageName,
					PackageManager.GET_UNINSTALLED_PACKAGES);
			if (pi != null) {
				installFlags |= PackageManager.INSTALL_REPLACE_EXISTING;
			}
		} catch (NameNotFoundException e) {
			Log.d("debug", "NameNotFoundException--" + e.getMessage());
		}
		PackageInstallObserver observer = new PackageInstallObserver();
		pm.installPackage(uri, observer, installFlags, packageName);
	}

	// 卸载
	public void uninstall(String packageName) {
		PackageManager pm = getPackageManager();
		PackageDeleteObserver observer = new PackageDeleteObserver();
		pm.deletePackage(packageName, observer, 0);
	}

	class PackageInstallObserver extends IPackageInstallObserver.Stub {
		public void packageInstalled(String packageName, int returnCode) {
			Message msg = mHandler.obtainMessage(INSTALL_COMPLETE);
			msg.arg1 = returnCode;
			mHandler.sendMessage(msg);
		}
	};

	class PackageDeleteObserver extends IPackageDeleteObserver.Stub {
		public void packageDeleted(boolean succeeded) {
			Message msg = mHandler.obtainMessage(UNINSTALL_COMPLETE);
			msg.arg1 = succeeded ? SUCCEEDED : FAILED;
			mHandler.sendMessage(msg);
		}
	}

	private Handler mHandler = new Handler() {
		public void handleMessage(Message msg) {
			switch (msg.what) {
			case INSTALL_COMPLETE:
				int centerTextLabel;
				Drawable centerTextDrawable = null;
				if (msg.arg1 == SUCCEEDED) {
				} else {
				}
				if (centerTextDrawable != null) {
				}
				break;
			default:
				break;
			}
		}
	};
}

此代码需要在sdk环境下编译（且本人用的System权限android:sharedUserId="android.uid.system"）

作者你好，我正在做这个功能，发现一个问题，我现在使用android1.5的sdk，为什么会出现 installFlags |= PackageManager.INSTALL_REPLACE_EXISTING;和 pm.installPackage(uri, observer, installFlags, "com.uc.browser");这两句话编译不通过，底下划着红线，而且我发现这种方法里只有三个参数，你这写的是四个。所以我有这样的疑问，当时你是怎么做的处理？请指教，谢谢
