29、简单的apk安装器

public class MainActivity extends Activity {
private EditText et_path;


@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et_path = (EditText) findViewById(R.id.et_path);
}

public void click(View view){

//path为apk的路径，如：http:192.168.137.1:8080/Server/haha.apk

String path = et_path.getText().toString().trim();
//安装apk
//        <intent-filter>
//        <action android:name="android.intent.action.VIEW" />
//        <category android:name="android.intent.category.DEFAULT" />
//        <data android:scheme="content" />
//        <data android:scheme="file" />
//        <data android:mimeType="application/vnd.android.package-archive" />
//    </intent-filter>
Intent intent = new Intent();
intent.setAction("android.intent.action.VIEW");
intent.addCategory("android.intent.category.DEFAULT");
intent.setDataAndType(Uri.fromFile(new File(path)), "application/vnd.android.package-archive");
startActivity(intent);
}
}
